Q. Why is steel unsuitable as the core of the electromagnetic?
If steel is used for making the core of an electromagnet, the steel does not lose all its magnetism when the current is stopped and it becomes a permanent magnet. Therefore steel is not used as the core of electromagnet. because steel is not a magnetic substance. the electromagnet needs magnetic substances.
Q. Can steel be used as a core for an electromagnet?
Originally Answered: Can a steel be used for making an electromagnet? Yes. Most inexpensive steel alloys will work quite well as the core material in an electromagnet. However, the steel core may retain significant magnetism after power is removed.

Q. Why is steel not used for making the core of an electromagnet Class 10?
The core of an electromagnet must be of soft iron because soft iron loses all its magnetism when current in the coil is switched off. Therefore, steel cannot be used for making the core of electromagnets.
Q. Which of these materials Cannot be used as core in electromagnets?
Iron, cobalt and steel are ferromagnetic materials which can be used to make magnet but ebonite cannot be used to make magnets. Was this answer helpful?
Q. What increases the strength of an electromagnet?
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. You can make a temporary magnet by stroking a piece of iron or steel (such as a needle) along a permanent magnet.
Q. How does the number of turns coils of wire affect the strength of electromagnet?
We can say that, the strength of the electromagnet is directly proportional to the number of turns in the coil. If you double the number of turns, you double the strength of the electromagnet.
Q. What is the effect of the size length of the wire on the strength of the electromagnet?
The magnetic field is caused by the current flowing in the wire. The bigger the current the stronger the magnetic field and hence the stronger the electromagnet.
Q. Which factor has the greatest effect on the strength of an electromagnet?
Q. How will they test the strength of their electromagnet with the materials they gathered How will Elly and Maggie increase the strength of their electromagnet?
They will have to measure the magnets strength by counting the number of paperclips your electromagnet can lift. They can also increase it by using more coils of wire, the number of dry cells also affects the strength of an electromagnet,more dry cells means more electrons flowing in the electromagnet.
Q. Which of the following will be attracted to an electromagnet?
Answer: Ferromagnetic metals are strongly attracted by a magnetic force. The common ferromagnetic metals include iron, nickel, cobalt, gadolinium, dysprosium and alloys such as steel that also contain specific ferromagnetic metals such as iron or nickel. Ferromagnetic metals are commonly used to make permanent magnets.
Q. What is the conclusion of electromagnet?
CONCLUSION. Electromagnets are very easy to build, and they can be controlled. They aren’t dangerous. They are more useful than regular magnets, and they work with electricity.
Q. What is the conclusion of magnetic lines of force?
If the compass needle rest in any direction at a certain point it shows that the net magnetic force acting on the point is zero. Hence, the resultant magnetic field is zero. This point is also known as null or neutral point.
Q. What is the conclusion of electric motor?
The electric motor works and how the power of electric magnetic forces help to provide energy. It shows how a magnet & coil wire can cause armature to spin.
Q. What is the conclusion of magnetic field?
It can be concluded that magnetic field at that point is zero. This is because the earth’s magnetic field at that point is neutralized by the magnetic field of some other magnetized material.
