Equal currents `i`, `i` are flowing through two infinitely long parallel wires. What will be the magnetic field at a mid-way, when the currents are flowing in same directions?

Equal currents i , i are flowing through two infinitely long parallel wires. What will be the magnetic field at a mid-way, when the currents are flowing in opposite directions?

A current I flows along the length of an infinitely logn, straight and thin walled pipe. Then, the magnetic field.

If a long copper rod carries a direct current, the magnetic field associated with the current will be

A current flows along the length of an infinitely long, straight, thin walled pipe. Then

what happens to the strength of magnetic field if currnt flowing in the wire is inereased?

Direct current cannot flow through.

A current of 5.0 A flows through each of two parallel long wires. The wires are 2.5 cm apart. Calculate the force acitng per unti length of each wire. Use standard value of constant required. What will be the direction of force, if both curents flow in the same direction?

What kind of magnetic field is produced by an infinitely long current carrying conductor?
