Magnetic field due to currentMedium
Question
Consider the magnetic field produced by a finitely long current carrying wire
Options
A.The lines of field will be concentric circles with centers on the wire
B.There can be two points in the same plane where magnetic fields are same
C.There can be large number of points where the magnetic field is same
D.The magnetic field at a point is inversely proportional to the distance of the point from the wire
Solution
The lines of force concentric circle with centers wire All points lying on the circle on the circle have same magnitude of magnitude field. magnetic field at a point front he wire varies inversely with distance from the wire.
