A long wire carries a current of `20A` along the directed axis of a long solenoid. The field due to a solenoid is `4mT`. Find the resultant field at a point `3mm` from the solenoid axis.

A long wire carries a current of 18 A kept along the axis of a long solenoid of radius 1 cm. The field due to the solenoid is 8 xx10 ^(-3)T. The magnitude of the resultant field at a point 0.6 mm from the solenoid axis is (Assume mu_(0) = 4pi xx 10 ^(-7)Tm//A)

Magnetic field B along the axis of a long solenoid is given by
