The magnetic field produced at the centre of a current bearing circular loop is directed
1.In the plane of the coil
2. normal to the plane of the coil
3. at 45degree with the plane of the coil
4.at 18degree with the plane of the coil

Hey Friend,
Ф Magnetic filed due to current through a circular loop -
1. The magnetic lines of force are concentrated near the coil where the current enters or leaves the coil.
2. Within the space enclosed by the coil, the lines of force are in same direction.
3. The magnetic field lines are parallel near center.
4. At the center of the coil, the plane of magnetic lines of force is at right angle to the plane of circular coil.
5. The intensity of magnetic field increases with the strength of current.
Ф Magnetic field due to a current in a solenoid -
1. A solenoid carrying current behaves like a magnet.
2. The magnetic field lines are parallel to each other within the solenoid and parallel to the axis of solenoid.
3. Intensity of magnetic field can be increased.
Hope it helps!
