Chapter 29: Q. 35 (page 832)

The right edge of the circuit in FIGURE EX29.35 extends into a 50mTuniform magnetic field. What are the magnitude and direction of the net force on the circuit?

Short Answer

Expert verified

The magnitude has 25mN and the direction is right.

Step by step solution

01

Step 1:Given Information

We have given the right edge of the circuit in the diagram extends into a 50mTuniform magnetic field.

02

Simplify

The current in the circuit is determined by Ohm's law

I=15v3惟=5A,

and its direction is shown in the figure below. The field points into the plane of the circuit. By right-hand rule. WE determine that the magnetic force

F鈫�=Il鈫�脳B鈫�

points to the right and has the magnitude

F=IlB=15mN.
