Dip circle used during Australasian Antarctic Expedition, 1911-14

This is a dip circle, a geophysical instrument used to determine the inclination of the Earth's magnetic field to the horizontal at a given location. It was manufactured by Moritz Meyerstein and is believed to have been used by Douglas Mawson on the Australasian Antarctic Expedition 1911-14. The instrument is 44.0 cm high, ...

Backyard Science: mysterious magnets

This resource provides opportunities for students to explore how a non-contact force, magnetism, interacts with everyday objects. Students will investigate the behaviour of a variety of materials when placed near a magnet and classify objects as magnetic or non-magnetic. Students will use their experiences to identify the ...

Understanding Magnets

In this simulation students select an object made of one of two materials (either iron or aluminium) and use magnets to guide the object through a maze. Engages students while they learn that aluminium is not attracted to magnets but iron is.

Interactive Resource

Magnetism and Electric Current

Students use this resource consisting of nine slides with diagrams, written explanation and voice-over to understand that wires carrying an electric current produce a magnetic field and that a current in a coil produces a magnetic field pattern similar to a bar magnet. There is a two-question quiz and a summary slide.

Electromagnetic Simulation (sk-Intel)

In this resource students explore how an electromagnet works in real life. They can then apply their learning in an electromagnetism game by changing the magnetism of a scrap lifter in a scrap yard and removing various amounts of scrap. The resource demonstrates the connection between the power applied, the number of coils ...

How does the number of batteries affect the strength of an electromagnet?

Find out how the strength of an electromagnet depends on the number of batteries connected to it. Choose a particular number of batteries and then test the strength of the electromagnet by inserting it into a container of paper clips. Observe the number of paper clips the electromagnet collects and record this in the data ...
