Physics : Magnetism 1
Overview
In this topic, students will cover the fundamental principles of magnetism, focussing on the magnetic field lines around a magnet and the Earth, the differences between permanent magnets and induced magnets, as well as the useful applications of magnets, e.g. in electromagnets and college bells.
The main SMSC/Personal Development content of this topic includes: PD15 – Sense of enjoyment and fascination in learning about themselves, others and the world around them.
PD20 – Working Scientifically Assessments and hinge questions as formative assessment.
The main UN Rights of a Child covered are No. 13 – Sharing thoughts freely and No. 17 – Access to Information.
Example Key Words
Magnetic Material
Materials that are affected by a magnet: steel, nickel, iron and cobalt.
Magnetic Field
The area around a magnet in which a non-contact force is exerted on another magnetic material. The arrows represent the direction in which a north pole would move.
Permanent Magnet
A magnet that cannot be turned off.
Induced Magnet
A material that becomes a magnet when it is placed within a magnetic field.
Electromagnet
An electromagnet consists of a solenoid and a core. When current passes through the solenoid, a magnetic field is generated.
