i have to design some physics labs
can anyone please help me with one please
1. aim : to test diode if effective
2. aim :to set up a simple electric circuit
3. aim: to make an electromagnet
4.aim:to test the polarity of a magnet
5.aim :to map a magnetic field of a bar magnet
thank you

I think is third option, because, in order to design an electromagnet, we have to make an iron bar, a coil which is used to surround the iron bar. Next we have to take a voltmeter, to measure the voltage at our coil, and an amperometer to measure the current which flows in our coil
