Question

at a given point on the cardboard the magnetic field produced by the current flowing through the coil is directly proportional to the current passing in coil and the ___ forming the coil​

Answer 1

Explanation:

From Biot-Savart law, magnetic field at a point p,

B

=

4π

μ

o

∫

r

3

I

dl

×

r

where r is the distance of point p from conductor and I is the current in the conductor.

Thus magnetic field due to current carrying conductor depends on the current flowing through conductor and distance from the conductor.
