what i have heard is that for the magnet question, u will have to note the angel of deflection by changing the voltage in wire. u will be given magnet attached with wooden stick which u will hang using stand and thread. then u will have to set up circuit. u will be provided with dc power supply n copper wire. u will position the wire in such way that it is below the magnet. then u will change the voltage, that will cause deflection in the magnet. then note the angel using protector..
plz do share ur guess about glass prism question.
