Magnets are usually metal, always metallic. A tool that cuts metal. A hacksaw for instance
Volt Metre is the apparatus used to detect the electricity generated. Moving a magnet in or around coil of enamelled copper wire or vice versa will generate electricity. The electricity generated can be detected, by connecting the ends of wires of coil to a Volt Metre. The Voltage generated proportional to the speed of movement and strength of the magnet, and the number of turns of the coil.
yes.when you slice a rod magnet it will still be considered as a magnet
No. You'll end up with two smaller magnets, and each will have less than half the magnetic field strength of the original magnet.
when a magnet is hardly rubbed on a iron ,for some time it reacts as a magnet. An example of a temporary magnet is used in acar breakers yeard . A crane fitted with amagnet picks up a car and then the power to the magnet is cut and the car drops.
The simplest detection of a magnetic field is done by another magnet. Or by an apparatus such as a Fluxgate magnetometer or similar.

vicats apparatus is used for initial setting time of cement.
A magnet
opposite poles
Cut one in half, and see if the two bits attract or repel one another. If they do, you have cut the magnet. Otherwise the rod. If you are allowed other equipment, you don't need to cut anything. Make a coil, connect to a meter, and see which rod, when pushed in and out of the coil, induces a current.
it becomes a magnet in it s own right with north and south poles
