The answer is A) sudeste.

the answer would be: el noroeste.

Answer: A compass needle points north because the north pole of the magnet inside it is attracted to the south pole of Earth’s built-in magnet. Since unlike poles attract, the thing your compass is being attracted to must be a magnetic south pole.

In the Compass Tool, first place the dot on the top line on the same coordinates as those from question 3 that match the path you chose for the boat. Move the blue dot on that line to point the needle in the same direction as the boat’s path. Hint: The lines will have the same direction if they are parallel.

When two like-poles point together, the arrows from the two magnets point in OPPOSITE directions and the field lines cannot join up. Unlike-poles attract: When a north pole and south pole point together, the arrows point in the SAME direction so the field lines can join up and the magnets pull together (attract).

When two magnets are brought together, the opposite poles will attract one another, but the like poles will repel one another. This is similar to electric charges. Like charges repel, and unlike charges attract.

Poles of a magnet One end is called the north pole, the other is called the south pole. If you line the magnets up so that two of the same poles face each other, the magnets will push away. This is called repulsion. Opposite poles attract each other, but similar poles repel.

Two magnets together will be slightly less than twice as strong as one magnet. When magnets are stuck entirely together (the south pole of one magnet is connected to the north pole of the other magnet) you can add the magnetic fields together.

Putting a piece of iron or steel inside the coil makes the magnet strong enough to attract objects. The strength of an electromagnet can be increased by increasing the number of loops of wire around the iron core and by increasing the current or voltage.

By adding one magnet on to the other, e.g. stacking, the stacked magnets will work as one bigger magnet and will exert a greater magnetic performance. As more magnets are stacked together, the strength will increase until the length of the stack is equal to the diameter.

It is possible to re-magnetize a magnet that has lost its magnetic properties, but as long as the alignment of its internal particles has not been modified for any reason, such as, for example, the exposure of these elements to high temperatures.

You brought up an interesting point. If we have two magnets made out of the same material and the material is magnetized the same, yet one magnet is thicker than the other, the thicker magnet will be stronger. That’s of course because there is more material there to act on an object out in front of the magnet.

The magnetic field is strongest at the center and weakest between the two poles just outside the bar magnet. The magnetic field lines are densest at the center and least dense between the two poles just outside the bar magnet.

The Insight-HXMT team has performed extensive observations of the accreting X-ray pulsar GRO J1008-57 and has discovered a magnetic field of ~1 billion Tesla on the surface of the neutron star. This is the strongest magnetic field conclusively detected in the universe.

Superconducting electromagnets These allow enormous currents to flow, which generate intense magnetic fields. Superconducting magnets are limited by the field strength at which the winding material ceases to be superconducting. Current designs are limited to 10–20 T, with the current (2017) record of 32 T.

Does an Electromagnet continually consume electricity? Yes, a typical copper wire electromagnet with an iron core consumes electricity constantly which is a waste of energy that is not required by the laws of physics to maintain force.

Electromagnets

• wrapping the coil around a piece of iron (such as an iron nail)
• adding more turns to the coil.
• increasing the current flowing through the coil.

What are 4 Ways to Make an Electromagnet Stronger?

• Increase more number of turns to the coil.
• Increase the flow of current through the coil.
• Wrap the coil around the iron piece.
• Increase in current or voltage.

1. Step 1: Materials Required. Here are the list of materials required for this project.
2. Step 3: Make a Solenoid Core Frame. It is important to make a Strong and sturdy frame for the electromagnet.
3. Step 4: Winding the Magnet Wire.
4. Step 5: Make the Circuit Connections.
5. Step 6: Testing the Electromagnet.

Increasing the magnetic field applied to the magnetizable material in turn makes its own magnetic field stronger. Similarly, wrapping with thicker wire has the same effect, but by increasing the current. Like a widening river, a thicker conductor allows more current through.

The strength of the magnetic field around a solenoid can be increased by: increasing the number of turns on the coil. increasing the current. placing an iron core inside the solenoid.

A solenoid is a long coil of wire wrapped in many turns. When a current passes through it, it creates a nearly uniform magnetic field inside. Solenoids can convert electric current to mechanical action, and so are very commonly used as switches.

Answer. Answer: Higher the number of turns, higher the length and thus the amount of current carrying coil material in use is higher and thus higher the magnetic field due to increased amount of current flowing through the solenoid as a result of the increased number of turns.

Voice coil actuators are typically used in focusing applications, oscillatory systems, mirror tilting, and miniature position control. Solenoids consist of a coil that is contained in a ferrous steel housing and a movable steel slug or washer. An electromagnetic field is generated by current being applied to the coil.

In a lot of cases, you will have to pay for multiple parts which can cost $1,000 or more on high-end cars. Since it can take hours to replace the actuator, you can expect to pay hundreds of dollars in labor, usually starting at around $300 and going up to $1,000 or more.

Solenoid valve is operated by electromagnetic coil, open or shut, time short. The operation of motorized valve is usually the motor, the time for open-shut can be adjusted. Solenoid valve is adapt to some special requirement, such as leakage, special medium. Motorized valve is usually adapt to adjustment.

A solenoid is a device comprised of a coil of wire, the housing and a moveable plunger (armature). When an electrical current is introduced, a magnetic field forms around the coil which draws the plunger in. More simply, a solenoid converts electrical energy into mechanical work.

While it’s not very common to have a bad starter solenoid, there are common signs of a bad starter solenoid, including hearing a rapid clicking sound from the starter solenoid, continuous rotation of the starter without engine starting, the starter cannot rotate, and drive gear reverses.
