Magnetic Fields Chapter 1 2023

Front

What is a magnetic field?

Back

A magnetic field is a region around a magnet where magnetic forces can be detected. It is represented by field lines that show the direction and strength of the magnetic force.

Front

What do opposite poles of magnets do?

Back

Opposite poles of magnets attract each other.

Front

What do like poles of magnets do?

Back

Like poles of magnets repel each other.

Front

What happens when you place two north poles of magnets together?

Back

They repel each other.

Front

What happens when you place two south poles of magnets together?

Back

They repel each other.

Front

What is the role of iron filings in studying magnetic fields?

Back

Iron filings align themselves along the magnetic field lines, visually demonstrating the shape and direction of the magnetic field.

Front

What is the direction of magnetic field lines?

Back

Magnetic field lines emerge from the north pole of a magnet and enter the south pole.

Front

What is the significance of the density of magnetic field lines?

Back

The density of magnetic field lines indicates the strength of the magnetic field; closer lines mean a stronger field.

Front

What is a magnetic pole?

Back

A magnetic pole is one of the two ends of a magnet where the magnetic force is strongest, typically referred to as the north and south poles.

Front

What is the principle of magnetic attraction and repulsion?

Back

The principle states that opposite poles attract and like poles repel.
