Demonstrates the properties of magnetic circuits with permanent magnets and pieces of soft iron. Shows how magnetic circuits can be shaped to give fields appropriate to particular devices and demonstrates...
Examines the fourth state of matter called plasma and how very hot plasma at temperatures of 100 million degrees can be contained and controlled by magnetic fields.
Part 1 explains the Lorentz force by considering a free-moving positively charged particle in a uniform magnetic field and the ‘right-hand’ screw is defined. The helical motion resulting from the...
Experiments using transparent electrolyte, mercury and liquid sodium-potassium alloy demonstrate the interactions between electro-magnetic and velocity fields which are central to magnetohydrodynamics.
