Magnets and Electromagnets

Projected KS4 Grades

  1.  

Compare the two types of waves and explain the similarities and differences between.

Draw particle models to help explain why conduction and convection cannot occur in different states of matter.

Apply your knowledge of forces to an unfamiliar context such as: the design a rollercoaster cart and explain how the design helps it travel fast.

Apply your knowledge to design a new electromagnetic circuit which could be used in an unfamiliar context. Explain you design.
