In the report, all the number will be taken in exact or 3 sig. fig.
Objective: Using a search coil and CRO to investigate the magnetic fields generated by alternating currents (A.C.) through a straight wire and a slinky solenoid.
Part A. Magnetic field around straight wire
Measuring the magnetic field generated 2cm away from the centre of the straight wire by search coil.
