In this lesson, we will learn how to calculate the magnitude of the magnetic dipole force that acts on a current-carrying loop in a uniform magnetic field.

Worksheet: Magnetic Force on a Current-Carrying Conducting Loop in a Magnetic Field • 9 Questions

Q1:

A 4.0-cm by 6.0-cm rectangular current loop carries a current of 10 A. What is the magnetic dipole moment of the loop?

Q2:

A conducting loop has 50 square turns with sides 15 cm long. The loop is placed in a uniform 0.80-T magnetic field. Find the current through the loop needed to create a maximum torque of 9.0 N.m.

Q3:

A 5.0-m section of a long, straight wire carries a current of 10 A while in a uniform magnetic field of magnitude T.
