Consider the magnetic field produced by a finitely long current carrying wire .

Options

A. The lines of field will be concentric circles with centres on the wire .
B. There can be points in the same plane where magnetic fields are same.
C. There can be large number of paints where the magnetic filed is same
D. The magnetic field at a point is inversally propotional to the distance of the point from the wire.

Answer

A,B,C

Explanation

If we take plane parallel to the length of wire function the all prints one plane will be current Field will be inversely proportional to the `bot` distance from the wire
