Question

1. Each of the four diagrams below shows a segment of a current-carrying wire in a magnetic field. Select the direction of the force on the wire from the following list:


A) up     B) down     C) left     D) right     E) into page     F) out of page     G) none of these     H) no force

2.   A 1.10 m long straight wire has a resistance R = 23.0 and is connected to a 6.00 V battery. The wire is located in a uniform magnetic field B directed perpendicular to the wire. Calculate the magnitude of B when the force on the wire due to B is 0.150 N.

Explanation / Answer


By using right hand rule

1) F

2) E

3) H

4) F

Answer : FEHF


2. R =23 ohms , V =6 V

from ohms law V =iR

i = 6/23 = 0.261 A

L =1.1 m

F = iLB

0.15 = (0.261*1.1*B)

B =0.5225 T
