A long straight wire carries a current of 35 A. What is the magnitude of the field B at a point 20 cm from the wire?

A current carrying wire produces a magnetic field in its surrounding space.Consider a tightly wound 100 turn coil of radius 10 cm, carrying a current of 1 A. What is the magnitude of the magnetic field at the centre of the coil ?

A Circular coil of wire consisting of 100 turns, each of radius 8.0cm carries a current of 0.40A. What is the magnitude of the magnetic field bar B at the centre of the coil?

Consider a tightly wound 100 turn coil of radius 10 cm, carrying a current of 1A. What is the magnitude of the magnetic field at the centre of the cell?

A long straight conductor carries 35 ampere. Find the magnetic field produced due to this conduc tor at a point 20 cm away from the centre of the wire.
