Magnets and Magnetic Fields

Question 1

Magnetic Field

Answer 1

A magnetic field is any region of space where magnetic forces can be felt. The direction of the magnetic field at a point is the direction of the force on a north pole if it were placed at that point.

Question 2

Magnetic Field Line

Answer 2

A line drawn in a magnetic field so that the tangent to it at any point shows the direction of the magnetic field at that point is called a magnetic field line

Question 3
