Edexcel IGCSE Physics 6.3 Hard and Soft Magnetic Materials Questions

Compare how readily iron and steel are magnetised or demagnetised, and use their different magnetic retention to explain which material suits a permanent magnet.

Exam points

Choose steel for a permanent magnet because hard magnetic materials are difficult to demagnetise and retain their magnetism.
Identify iron as a magnetically soft material and explain that it loses its magnetism when the external field is removed.

[Maximum number: 1]
