A straight current carrying conductor is kept along the axis of circular loop carrying current. The force exerted by the straight conductor on the loop is :
1 zero
2 perpendicular to the plane of the loop
3 in the plane of the loop, away from the centre
4 in the plane of the loop, towards the centre
Explanation:
A Magnetic field due to straight current carrying conductor is concentric circles which is parallel to be plane of the loop. Hence, required force is zero.

A current carrying conductor produces
1 only electric field
2 only magnetic field
3 both electric and magnetic fields
4 neither electric nor magnetic field
Explanation:
B If current (i) is flow through the wire, it will produce only magnetic field.

A charged particle is released from rest in a region of uniform electric and magnetic fields which are parallel to each other. The particle will move on a:
1 Straight line
2 circle
3 helix
4 cycloid
Explanation:
A If a charged particle is released from rest in a region of uniform electric and magnetic field parallel to each other, it will move to straight line.

An electron enters a region where magnetic field (B) and electric field (E) are mutually perpendicular, then
1 it will always move in the direction of $B$
2 it will always move in the direction of $\mathrm{E}$
3 it will always possess circular motion
4 it can go undeflected also
Explanation:
D The deflection produced by electric field is nullified by deflection produced by magnetic field. Hence, electron enters a region where magnetic and electric field is mutually perpendicular, then it can go undeflected.

The two parallel wires carry current in opposite directions
1 the wires attract each other
2 the wires repel each other
3 the wires experience neither attraction nor repulsion
4 the forces of attraction or repulsion do not depend on current direction
Explanation:
B If two parallel wires carry current in opposite direction, they repel each other where as if two parallel wire carry current in same direction they attract each other.
