Every electrical current produces a magnetic field.

An electric current will produce a magnetic field, which can be visualized as a series of circular field lines around a wire segment.

A current traveling through a loop of wire creates a magnetic field along the axis of the loop. The direction of the field inside the loop can be found by curling the fingers of the right hand in the direction of the current through the loop; the thumb then points in the direction of the magnetic field.

the electric and magnetic fields are generated by moving electric charges, the electric and magnetic fields interact with each other, the electric and magnetic fields produce forces on electric charges, the electric charges move in space.

One finds the ‘B’ used most often with MRI systems and is seen as dB/dt which is an expression of the change in amplitude over the change in time. ‘B’ being the amplitude or intensity of the field.

On Earth, flowing of liquid metal in the outer core of the planet generates electric currents. The rotation of Earth on its axis causes these electric currents to form a magnetic field which extends around the planet. The magnetic field is extremely important to sustaining life on Earth.

The definition of H is H = B/μ − M, where B is the magnetic flux density, a measure of the actual magnetic field within a material considered as a concentration of magnetic field lines, or flux, per unit cross-sectional area; μ is the magnetic permeability; and M is the magnetization.

The International System (SI) unit of field intensity for magnetic fields is Tesla (T). One tesla (1 T) is defined as the field intensity generating one newton of force per ampere of current per meter of conductor: T = N · A-1 · m-1 = kg · s-2 · A-1.

Biot-Savart’s law is an equation that gives the magnetic field produced due to a current carrying segment. where km is the magnetic constant that has a value 10-7 T-m/A. …

B is magnetic flux density, whereas H is magnetic field intensity. H has units of amp-turn/meter, whereas B has units of weber/turn-meter^2. In non-ferrous materials they have a simple inter-relation given by B = mu*H.

At each end of a magnet is a pole. These lines of flux (called a vector field) can not be seen by the naked eye, but they can be seen visually by using iron fillings sprinkled onto a sheet of paper or by using a small compass to trace them out.

Magnetic flux is a measurement of the total magnetic field which passes through a given area. It is a useful tool for helping describe the effects of the magnetic force on something occupying a given area. The measurement of magnetic flux is tied to the particular area chosen.

Researchers have also found some specialized cells in birds’ eyes that may help them see magnetic fields. It is thought that birds can use both the beak magnetite and the eye sensors to travel long distances over areas that do not have many landmarks, such as the ocean.

Quantity that is not affected by magnetic field is Stationary charge.

Gamma ray is electromagnetic wave which is neutral. So gamma ray is not affected by electric and magnetic field.

3 Answers. An applied electric or magnetic field doesn’t alter the field of an electromagnetic field because, as you said, the superposition principle holds. This principle is a principle of linearity, and comes from the linearity of electromagnetic equations : there is no interaction between photons at low energies.

Any changing magnetic field generates a changing electric field and that produces an electromagnetic wave. Electromagnetic (EM) waves cannot interact directly with light photons since photons have no charge.

Electromagnetic (EM) radiation is a form of energy that is all around us and takes many forms, such as radio waves, microwaves, X-rays and gamma rays. Sunlight is also a form of EM energy, but visible light is only a small portion of the EM spectrum, which contains a broad range of electromagnetic wavelengths.

yes, as light is electromagnetic wave therefore it can be deviated from its straight path by applying highly non uniform magnetic field.

The laser intensity decrease observed at large magnetic fields in the computation that excludes the Zeeman effect is the result of a smaller gain caused by a decrease in the density, reduced transient effects associated with ionization and excitation, and an increase in the optical depth.

Electrodynamics is the physics of electromagnetic radiation, and electromagnetism is the physical phenomenon associated with the theory of electrodynamics. The electromagnetic fields of light are not affected by traveling through static electric or magnetic fields in a linear medium such as a vacuum.

Definition: Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. EM waves travel with a constant velocity of 3.00 x 108 ms-1 in vacuum. They are deflected neither by the electric field, nor by the magnetic field.

Electromagnetic waves are members of a family of waves with common properties called the electromagnetic spectrum. All electromagnetic waves: are transverse waves; can travel through a vacuum ; travel at exactly the same speed in a vacuum, the speed of light, 300,000,000 m/s.

Alpha particles are positively charged, beta particles are negatively charged, and gamma radiation is electrically neutral . This means that alpha and beta radiation can be deflected by electric fields , but gamma radiation cannot. Remember that opposite charges attract.
