What is a magnetic field?
Q: What is a magnetic field?
A: A magnetic field is an area around a magnet in which there is magnetic force, created by moving electric charges.
Q: How can the strength of a magnet be determined?
A: The strength of a magnet can be determined by looking at the spaces between the magnetic flux lines - the closer they are together, the stronger the magnet will be.
Q: What happens when particles touch a magnetic field?
A: When particles touch a magnetic field, they are given power from it.
Q: What does it mean for something to have its own energy and momentum?
A: Having its own energy and momentum means that something has its own properties that allow it to move or act independently from other objects or forces.
Q: How is the strength of a magnetic field measured?
A: The strength of a magnetic field is measured in units of teslas (SI units) or gauss (cgs units).
Q: Who founded the law of electromagnetism?
A: Michael Faraday founded the law of electromagnetism.
Q: What happens when iron filings are placed near a magnet?
A: When iron filings are placed near a magnet, they move and arrange into flux lines that show the direction and strength of the magnetic field.
