Question

What is magnetic field? On what factors does it depend?​

Answer 1

Hey,

Explanation:

What is magnetic field

～～A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. Magnetic fields surround magnetized materials, and are created by electric currents such as those used in electromagnets, and by electric fields varying in time～～

factors depends on

• It encircles the conductor.
• It lies in a plane perpendicular to the conductor.
• Reversal in direction of current flow reverses the direction of the field.
• Strength of the field is directly proportional to the magnitude of current.
• Strength of the field at any point is inversely proportional to the distance of the point from the wire.

Hope it's helpful!!
