What are the two types of poles found in every magnet?

North and South poles

True or False: Like magnetic poles attract each other.

False; like poles repel each other.

Fill in the blank: The magnetic field lines emerge from the ___ pole and converge at the ___ pole.

North; south

What happens to the direction of the compass needle when an electric current passes through a metallic conductor?

The compass needle gets deflected.

Explain the right-hand thumb rule in relation to current-carrying conductors.

If you hold a current-carrying straight conductor with your right hand, with your thumb pointing in the direction of the current, then your fingers curled around the conductor show the direction of the magnetic field.

Fill in the blank: A solenoid acts like a magnet with one end as the ___ pole and the other as the ___ pole.

North; south

What results when a live wire comes into direct contact with a neutral wire?

A short circuit occurs.

True or False: The Earth wire provides a high resistance path to protect against electric shock.

False; the Earth wire provides a low resistance path for current in case of leakage.

What is an electromagnet?

An electromagnet is a magnet created by electric current passing through a coil, which can magnetize materials placed within it.

Fill in the blank: The intensity of the magnetic field is indicated by the proximity of the ___ lines.

Field

What happens to the magnetic field strength as you move further from a current-carrying wire?

The magnetic field strength decreases as you move farther from the wire.

Describe how the magnetic field inside a solenoid differs from that outside.

Inside a solenoid, the magnetic field lines are straight and parallel, indicating a uniform and strong field, while outside, the field is weaker and diverges.

What is the potential difference between the live and neutral wire in India?

220 V

Fill in the blank: The magnetic field lines do not ___ because it would indicate multiple directions at one point.

Intersect

How can the direction of motion or force on a current-carrying conductor in a magnetic field be determined?

By using Fleming’s Left-Hand Rule.

What is the effect of overloading in an electric circuit?

Overloading occurs when the current drawn exceeds the conductor's carrying capacity, leading to potential hazards.
