stable triggering to 30 MHz

dimensioned to hold a pair of 150mm (6-inch) bar magnets safely apart from other steel apparatus while preserving the polar alignment of each

Demonstrates that charge resides only on the outer surface of a conductor by inverting the charged net inside out and showing the charge transferring to the new outside layer
