Electromagnetism

Question 1

Define magnetic field

Answer 1

Magnetic field is a region of space where a current-carrying conductor, magnetic material or a moving charge in it experiences a magnetic force.

Question 2

Define magnetic flux density

Answer 2

Magnetic flux density at a given point in a magnetic field is defined as the magnetic force per unit length exerted on a long straight conductor carrying a unit current perpendicular to the magnetic field.
