Question

Find the force due to a current element of length 6cm and flux density of 12 tesla. The current through the element will be 10A.

Answer 1

7.2 N

Step-by-step explanation:

Applying,

F = BIL................. Equation 1

Where F = Force due to current through the element, B = magnetic field, L = Length of the element.

From the question,

Given: B = 12 Tesla, L = 6 cm = 0.06 m, I = 10 A

Substitute these values into equation 1

F = 12(0.06)(10)

F = 7.2 N

Hence the force through the element is 7.2 N
