A straight wire 15cm long, carrying a current of 6.0A is in a uniform field of 0.40T. what is the force on the wire when it is at right angle to the field?

  • A. 0.46N
  • B. 0.35N
  • C. 0.36N
  • D. 0.24N

QUICK ANSWER…

C

DETAILS…

The force experienced by a current carrying conductor placed in a magnetic field can be calculated using the following formula:

F = BILsinx

Where F = force experienced by the conductor = ?

B = magnetic field = 0.4T

I = current = 6A

L = length of the conductor = 15cm = 15/100 = 0.15m

x = angle between the field direction and the current direction = right angled = 90degrees.

Substituting these values, we have:

F = BILsinx

F = 0.4 X 6 X 0.15 X sin90

F = 0.4 X 6 X 0.15 X 1 = 0.36N

Now for the right answer to the above question:

  1. Option A is incorrect.
  2. Option B is incorrect.
  3. C is correct.
  4. D is not the correct answer.

KEY-POINTS…

You may please note these/this:

  • The force experienced by a current carrying conductor placed in a magnetic field can be calculated with this equation: F = BILsinx.
