How do forces affect speed, shape or direction of objects?
When a force is applied to an object, it can cause it to start moving, accelerate, decelerate, change direction, or even change its shape.
What are the properties of magnetically hard materials?
Magnetically hard materials are difficult to magnetize and retain their magnetism
What are the properties of magnetically soft materials?
Magnetically soft materials are easily magnetized and lose their magnetism when the external magnetic field is removed
When is magnetism caused?
When some materials are placed in a magnetic field
