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
