PHY137H5 Lecture Notes - Lecture 6: Solar Wind, Magnetic Monopole, Centripetal Force
Document Summary
Relevance areas where objects have a magnetic influence like electric charges, unlike magnetic poles attract and like poles repel here"s what happens when you cut a magnet: All magnets are dipolesthere aren"t any magnetic monopoles (that we know of). consequently. one end acts as a source and the other as a sink. What is it used for? magnetic fields are used in permanent magnets and electromagnets. the earth also has a magnetic field. Keeps liquid water on earth (mars lost it"s water because its magnetic field wasn"t strong enough to hold the atmosphere. with no atmosphere, liquid water just boils off, regardless of temperature) What is it used for? mass spectrometers use magnetic forces the hall effect. How does it work? the magnetic force is a key component of the. Hall effect, which itself is important because it is what tells us that the current is made up of negative charges.
