## Important Topics for HC Verma Concepts of Physics Part-2 Solutions Chapter 34: Magnetic Field

Magnetic Field

A magnetic field is a field of the vector that defines the magnetic effect of electric charges in relative motion and magnetized constituents. A charge that is moving parallel to a current of other charges practices a force perpendicular to its own velocity.

Difference between Electric and Magnetic Fields

Electric Field

• It generates an electric charge in the atmosphere
• Calculated as newton per coulomb, volt per meter
• It is proportional for the electric charge
• They are perpendicular to the magnetic field
• The electric field is calculated using an electrometer

Magnetic Field

• It generates an electric charge around moving magnets
• Calculated as gauss or tesla
• It is proportional to the speed of electric charge
• They are perpendicular to the electric field
• The magnetic field is calculated using a magnetometer

Torque on a Current Loop

A uniform magnetic field applies no net force on a current loop but it does apply a net torque. Let’s suppose, the magnetic field is in the plane of the loop and is parallel to two sides. If the loop has a width x, x-height y, and x current I, then the force on each of the left and right sides is F = IBB.

Magnetic Force On a Current-carrying Wire

The magnetic field applies a force on a current-carrying wire in a direction provided by the right-hand rule 1 (the same direction as that on the individual moving charges). The force on an individual charge moving at the drift velocity ‘VD’ is represented by

F = qvdB sin θ
