Electromagnet or Magnet?
Contrast temporary and permanent magnets from experimental evidence.
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 65
- A bar magnet is a permanent magnet. It keeps its pull with no electricity.
- An electromagnet is a temporary magnet. It only pulls while current flows.
- Here's the evidence. Stop the current, and an electromagnet drops the clips. A bar magnet keeps holding on.
- Both have magnetic fields, and both pull iron and steel. The difference is control.
Georgia Standards of Excellence in Science:
- S5P3.a β Construct an argument based on experimental evidence to communicate the differences in function and purpose of an electromagnet and a magnet. (Clarification statement: Function is limited to understanding temporary and permanent magnetism.)
