Kerala Board Solutions for Chapter: Magnetic Effect of Electric Current, Exercise 1: Let us assess

The figure given below shows an insulated copper wire AB made into a coil. Suppose current flows from A to B through this. Can you find the direction of magnetic field around the conductor AB? State the rule substantiate this.

The magnetic field around the current carrying conductor AB is depicted.

Based on the Maxwell's Right Hand Cork Screw Rule, find out the direction of current.

Electricity flows through a very long solenoid. Some statements are given below related to the magnitude of the magnetic field developed inside the solenoid. Find the correct one.

The direction of movement of electrons through a magnetic field is depicted in the figure given below.

"The force felt by the electrons due to the influence of the magnetic field is into the plane of the paper". Is this statement correct? Explain based on the Fleming's Left Hand Rule.

In an experiment to know the intensity of magnetic field around a current carrying coil, why is the coil kept in North South direction.

In a split ring commutator of a DC motor, semi-circular rings are used. What is the need for this?

A current carrying solenoid is stretched to increase the distance between the coils. What change will occur in its magnetic field? Describe.

State the motor rule. If the direction of current in the conductor and the magnetic field are the same, in which way the conductor move?
