An electric charge attracts the compass needle. A magnetic field is generated around the current carrying wire. The electric current changes the earths magnetic field. The group compares the results of this experiment and previous ones to their hypotheses in an effort to identify any hypothesis that doesn't fit with all the experimental findings. We have to come up with a theory that explains how magnetism can act at a distance.
Electrical charges affect compasses.
Magnetic fields are generated around current carrying wires, and this causes the magnetic poles of the compass needle to be attracted. Electric current in a wire affects the earth's magnetic field which then affects the magnetic pole of the magnet. The hypotheses are accepted or rejected by the class, using the experimental findings as a reference. A condition in a region of space caused by either a magnet or an electric current where a detectable magnetic force exists. Test your hypotheses.
