Arectangular current loop (a = 16.0 cm, b = 30.0 cm) is located a distance d = 14.0 cm near a long, straight wire that carries a current ( i w ) (iw) of 10.0 a (see the drawing). the current in the loop is i l il = 20.0 a. determine the magnitude of the net magnetic force that acts on the loop.

The magnitude of the net magnetic force is

Explanation:

Given that,

Distance = 14.0 cm

Side a = 16.0 cm

Side b = 30.0 cm

Current

Current

According to figure,

Force F₂ and F₄  balance by each other

So, We need to calculate the magnetic force

Using formula of magnetic force

Put the value into the formula

The direction of force is downward.

For F₃,

We need to calculate the magnitude of the net magnetic force that acts on the loop

Using formula of net magnetic force

Put the value into the formula

The direction of net force towards the wire.

Hence, The magnitude of the net magnetic force is
