Determine the magnetic field at point P ...

Determine the magnetic field at point `P` located a distance `x` from the corner of an infinitely long 2. Wire bent at right angle as shown in figure. The wire carries a steady current i.

Text Solution

Verified by Experts

Magnetic field due to horizontal wire is zero.
Magnetic field due to vertical is
`B=mu_0/(4pi) i/x (sin90^@ +sin0^@)`
`=mu_0/(4pi) i/x` (inwards)`
