The earth has a giant magnetic field caused by the liquid iron that constantly moves in the outer core. Scholars explore the magnetic fields of four different planets. The strength and alignment of the poles relates to the implications...

Six simple images pull your class into magnets. Most of the pictures show magnetic fields as revealed by iron filings. Concepts are explained in print along the bottom of each slide and include magnetic force, force fields, poles,...

You'll be strangely drawn to this activity! Physical science pupils learn how compasses work in an interesting interactive. The content covers magnetic poles, Earth's magnetic field, and what would happen if Earth's poles swapped places.

Michael Faraday was self-educated, earned an honorary doctorate from the University of Oxford, invented the first Bunsen burner, discovered the laws of electrolysis, and proved that a changing magnetic field produces a current. In this...

What is the largest electric field in the world? The world itself! This explains why you use a magnetic compass to determine direction. During the simulation, scholars add charges to their electric field to see how the field reacts....

In this electromagnetism and electromagnetic induction worksheet, students answer 12 questions about electricity, about the magnetic fields in given diagrams, about the right-hand rule and about electric current and voltage in magnetic...

Students explore the magnetic field surrounding a simple bar magnet. They can drag the compass around in the space surrounding the bar magnet, and observe the effect of the magnet on the compass needle.

Explore the interactions between a compass and bar magnet. Discover how to use a battery and wire to make a magnet.

Move a bar magnet or an electromagnet around to see how the magnetic fields change. Requires Java.

Ever wonder how a compass worked to point you to the Arctic? Explore the interactions between a compass and bar magnet, and then add the earth and find the surprising answer.
