# Two Large Metal Sheets Carry Currents as Shown in Figure. the Current Through a Strip of Width Dl Is Kdl Where K is a Constant. Find the Magnetic Field at the Points P, Q And R. - Physics

Short Note

Two large metal sheets carry currents as shown in figure. The current through a strip of width dl is Kdl where K is a constant. Find the magnetic field at the points P, Q and R.

#### Solution

At point P,
Current, i = 0
∴ Magnetic field B = 0
At point Q,
Applying Ampere's law, we get

int B .dl = mu _0i

⇒ B .dl = mu _0 kdl

⇒ B= mu _0k

At point R,
Current, i = 0
∴ B = 0

Is there an error in this question or solution?
