Question

A) What is the direction of the magnetic field at the center of the loop made by the current I?

Out of the page

Into page

up

down

B) In what direction will the loop rotate due to the torque from the external magnetic field?

clockwise

counter clockwise

In the equation we use to find the torque on a loop sitting in an external magnetic field, which angle is used in "sin?"?
The angle between a line perpendicular to the plane of the loop and the magnetic field the loop sits in.
The angle between a line perpendicular to the plane of the loop and the magnetic field made by the loop.
The angle between a line in the plane of the loop and the magnetic field made by the loop.
The angle between a line in the plane of the loop and the magnetic field the loop sits in.

D) What is the magnitude of the magnetic torque exerted on the loop in the figure?

0.00964 0.0110 0.00351 0.0303 0.0322

Explanation / Answer

Part A)

By the right hand rule, the current direction is DOWN

Part B)

By the right hand rule, the torque will cause a COUNTER-CLOCKWISE Spin

Part C)

The angle between a line perpendicular to the plane of the loop and the magnetic field the loop sits in.

Part D)

Torque = BIAsin(angle)

Torque = 2(5.7)(pi)(.03)2(sin 70)

Torque = .0303
