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
