1.	The magnetic field lines inside a solenoid are in the form of parallel straight line the reason for this is the magnetic field inside the solenoid isa) very highb) uniformc) zerod) produced by electricity
Answer» b) uniform The MAGNETIC field inside a LONG solenoid is uniform because of the fact that by Biot Savart's LAW, the direction of magnetic is in the direction of the cross product of the current element and the RADIUS VECTOR.
