A charged particle enters at right angles into a uniform magnetic field as shown. What should be the nature of charge on the particle if it begins to move in a direction pointing vertically out of the page due to its interaction with the magnetic field?

What will the polarity be one end of a solenoid if the current appears to be flowing anticlockwise in it?

The diagram shows a coil of wire wound on a soft iron core forming an electromagnet. A current is passed through the coil in the direction indicated by the arrows. Mark the N and S-poles produced in the iron core.

State and explain Fleming's right hand rule.

Meena draws magnetic field lines of field close to the axis of a current carrying circular loop. As she moves away from the center of the circular loop she observes that the lines keep on diverging. How will you explain her observation?

In the simple electric motor of figure given below, the coil rotates anticlockwise as seen by the eye from the position X when current flows in the coil.

Is the current flowing clockwise or anticlockwise around the coil when viewed from above?

Which way does the wire in the diagram below tend to move?
