Magnetic Effect...

Particles having positive charge occasionally come with high velocity from the sky towards the earth on account of magnetic field of earth, they would be deflected towards:

The lines of force of a bar magnet are:

If the key in the arrangement is taken out (the circuit is made open) and magnetic field lines are drawn over the horizontal plane ABCD, the lines are:

A long solenoid with closely spaced turns carries a direct electric current. Each turn of wire exerts:

The laws of electromagnetic induction have been used in the construction of a :

A proton is projected horizontally eastward in a uniform magnetic field, which is horizontal and southward in direction. The proton will be deflected

The incorrect statement regarding the lines of force of the magnetic field B is:

For a current in a long straight solenoid N- and S-poles are created at the two ends. Among the following statements, the incorrect statement is:

In the arrangement shown in the figure, there are two coils wound on a non-conducting cylindrical rod. Initially, the key is not inserted. Then the key is inserted and later removed. Then :

If the forefinger shows the direction of the magnetic field and the thumb indicates the motion of the conductor, then, according to Flemings left-hand rule, what does the middle finger point at?
