Magnetic Closure Box and Field Patterns

This page introduces magnetic field patterns and forces between magnets using the example of a magnetic closure box.

The diagram shows two magnets with north and south poles on their longer faces. Students are asked to draw the magnetic field pattern between the facing poles and explain why the magnets must not have two north poles facing each other.

Definition: Magnetic field patterns show the direction and strength of the magnetic force around magnets using field lines.

Highlight: Understanding magnetic field patterns is crucial for GCSE Physics magnetism and electromagnetism exam questions.

Investigating Magnetic Forces

This section covers an experiment to investigate how the force of attraction between two bar magnets depends on their separation.

The procedure involves using a newtonmeter to measure the force required to separate two magnets with varying numbers of paper sheets between them. Students analyze the results and suggest improvements to the experimental method.

Example: As the number of paper sheets (separation) increases, the force required to separate the magnets decreases.

Vocabulary: Newtonmeter - an instrument used to measure force.

Magnetic Fields and Non-Contact Forces

This page explores the concept of non-contact forces in magnetism and how to plot magnetic field patterns.

Students are asked to explain what is meant by "A non-contact force acts on each magnet" when two bar magnets are suspended close to each other. They also need to describe the process of plotting a magnetic field pattern for a bar magnet.

Definition: A non-contact force is a force that acts between objects without them physically touching, such as magnetic or gravitational forces.

Highlight: Understanding how to plot magnetic field lines GCSE is essential for visualizing magnetic interactions.

Electromagnets and Motion

This section introduces electromagnets and their effects on the motion of magnetic objects.

A diagram shows an experimental setup with a steel ball-bearing, an iron rod, and an electromagnet. Students explain how closing a switch affects the motion of the ball bearing, demonstrating the interaction between electromagnets and magnetic materials.

Vocabulary: Electromagnet - a type of magnet in which the magnetic field is produced by an electric current.

Induced and Permanent Magnets

This page discusses the difference between induced and permanent magnets using the example of iron nails hanging from a bar magnet.

Students complete a sentence to describe how the iron nails become magnetized and identify which of three metal bars in a diagram is an unmagnetised piece of iron based on the forces between them.

Definition: Induced magnetism occurs when a magnetic material becomes temporarily magnetized in the presence of a magnetic field.

Highlight: Understanding the difference between induced and permanent magnets is crucial for AQA GCSE Physics Magnetism and electromagnetism exam questions.

Investigating Fridge Magnet Strength

This section covers an investigation into the strength of different fridge magnets using sheets of paper.

Students analyze the results of an experiment measuring the number of paper sheets each magnet can hold and evaluate a hypothesis about the relationship between magnet area and strength.

Example: The results show that the magnet with the largest area (1350 mm²) held the fewest sheets of paper (4), contradicting the hypothesis.

Highlight: This practical activity helps students understand how to design and evaluate experiments for AQA GCSE Physics required practicals Paper 2.

Electromagnet Strength Investigation

This page introduces an investigation into factors affecting electromagnet strength.

The diagram shows three electromagnets with different numbers of wire turns. Students are asked to complete a conclusion about how increasing the number of turns affects electromagnet strength.

Vocabulary: Electromagnet - a temporary magnet created by passing an electric current through a coil of wire wrapped around an iron core.

Highlight: Understanding factors affecting electromagnet strength is essential for Magnetism and Electromagnetism notes pdf and exam preparation.
