A 240-m length of wire stretches between two towers and carries a 120-A current. Determine the magnitude of the force on the wire due to the Earth’s magnetic field of 5.0× 10-5 T which makes an angle of 680 with the wire.
Force on a straight wire of length 240 m carrying current 120 A and making angle of 68o with earth’s magnetic field of 5 X 10-5 T.
Answer to Problem 3P
Solution:
Force = N
Explanation of Solution
Given:
Current I = 120 A; Magnetic field B = 5X 10-5 T; Length =240m and Ϙ = 68o
Formula Used:
Calculation:
In order to find the value of force on current carrying conductor, we have to use the equation,
=
=
=
