Question

A 10 V force acts on a rectangular conductor of 5 cm long placed perpendicular to a magnet
field. If the current in conductor is 50 A. then B
(2) 2.5 tesla
(3) 25 tesla
(4) 4 tesla
(1) 0.4 tesla
​

Answer 1

Explanation:

Given :

Force =10N

Length of the conductor= 5cm=5/100 m

Current =I=50 A

B=?

Use the formula

F=BIL

B=F/IL

=10x100/50x 5

=4 Tesla

Therefore B= 4 tesla

Answer 2

Answer:

Given:-

• Voltage=10V
• Current=50A
• length=5cm=0.05m

To find:-

• B=?

Find:-

As we know that F=BIL

B=F/IL

B= 10*100/50*5

B=4tesla.

Hence C is the right ans❤
