Blocking magnetic force
I can explore different materials to investigate if magnetic force can be blocked.
Lesson details
Key learning points
- Magnetic forces can act at a distance when some materials are placed between the magnet and the magnetic material
- Scientists can carry out investigations to test which materials allow magnetic force to pass through
- Sometimes the results of an investigation are different to what was expected or predicted
Keywords
Magnetic force - Magnetic force is the force caused by a magnet.
Block - To block something is to stop it from moving or having an effect.
Non-contact force - A non-contact force is a force which occurs when objects are not touching each other.
Material - A material is the thing that objects are made from such as wood.
Predict - To predict is to say what you think will happen.
Common misconception
Magnets can exert a force through paper, but not wood, a table, or other thick materials.
Explicit teaching and investigation will clarify that magnetic force can act through a range of materials.
