A straight vertical conductor carries a current. At a point `5cm` due north of it, the magnetic induction is founded to be `20muT` due east. The magnetic induction at a point `10cm` east of its will be

At a point on the exial of a magnet,the magnetic at a induction is found to be 80 muT .The induction at a point on its equatorial line at twice the distance of the first point will be

A long straight vertical conductor carries a current of 8A in the upward direction. What the magnitude of the resultant magnetic induction at a point in the horizonatal plane at a distance of 4 cm from the conductor towards South? (The horizontal compo-nent of earth's magnetic induction =4 xx 10^(-5)T )

The magnetic field induction at a point due to a current element is given by

What is a toroid? Calculate the magnetic induction at a point due to current in toroid.
