Chapter 22 Magnetism - Physics & Astronomy
In magnetism: B= F /q v sin θ Units of B: Tesla (T) 1 Gauss = 10-4 T Magnetic fields (B fields) point towards south poles and away from north poles Force on a moving charged particle when it enters a magnetic field The particle experiences a force that is evident because the charge is deflected from its original path
Lecture 8: Magnets and Magnetism - Montana State University
Electron theory of magnetism •Electrons spin as they orbit (similar to earth) •Spin produces magnetic field •Magnetic direction depends on direction of rotation •Non-magnets → equal number of electrons spinning in opposite direction •Magnets → more spin one way than other
Chapter 20 Magnetism
Magnetism 20 1 Magnets and Magnetic Fields Magnets have two ends – poles – called north and south Like poles repel; unlike poles attract 20 1 Magnets and Magnetic Fields However, if you cut a magnet in half, you don’t get a north pole and a south pole – you get two smaller magnets 20 1 Magnets and Magnetic Fields
Chapter 8: Magnetism & Electromagnetism
Learning with Purpose Slide 8 To measure magnetic fields, an instrument called a gaussmeter is used The gauss is a unit of flux density and is a much smaller unit than the tesla (1 G = 10-4 T)
