Question

How magnetic field is created?

Answer 1

Explanation:

Magnetic field: The action of magnetism on moving electric charges, electric currents, and magnetic materials is explained by a magnetic field, which is a vector field.

1. A travelling charge encounters a force that is perpendicular to both its own velocity and the magnetic field.
2. Moving electrically charged particles produce a magnetic field.
3. Changing electric fields can also produce magnetic fields.
4. For a current carrying conductor, the current flowing through the wire determines the strength of magnetic field.
