The direction of electric current in a solenoid when viewed from a particular end is anticlockwise, then this end of solenoid will be :

Field at one end of a solenoid is

Field at one end of a solenoid is

Why does a current-carrying solenoid when suspended freely rests along a particular direction?

Give reasons for the following: The current carrying solenoid when suspended freely rest along a particular direction.

At a small distance from a solenoid carrying a current thero is placed a contour with a current in such a manner that the solenoid's axis lies in the plane of the contour. The directions of the currents in solenoid and contour are shown by arrows. How docs the contour move? I-Iow will it IJlOVe if the current in it flows in the direction opposite to the one shown in the figure?

If a solenoid is bent in a circular shape and the ends are joined, we get _.

When the current through a solenoid increases at a constant rate, the induced current in the solenoid

When the current through a solenoid increases at a constant rate, the induced current in the solenoid
