Question

what is magnetic field​

Answer 1

Answer:

Magnetic fields force moving electrically charged particles in a circular or helical path. This force—exerted on electric currents in wires in a magnetic field—underlies the operation of electric motors. (For more information about magnetic fields, see magnetism.

Answer 2

Question:-

What is Magnetic Field ?

$\:$

Answer:-

The area around a magnet where a magnetic force is experienced is called the magnetic field.

$\:$

Explanation:-

Magnetic field lines are imaginary lines around the magnet. The magnitude of a field is indicated by its line's density. Near to South and North Pole of a magnet, the magnetic field is stronger and will get weaker when it moves away from the poles.

The Biot-Savart Law can be used to determine the magnetic field strength from a current segment. For the simple case of an infinite straight current-carrying wire it is reduced to the form B=μ0I2πr B = μ 0 I 2 π r .
