As we saw in Checkpoint 30.9, a receiving dipole antenna has to be aligned with the oscillating electric field in order to produce a measurable potential difference in the antenna. What if we wanted to detect the potential difference caused by the changing magnetic field?

(a) What antenna shape would we need?

(b) How would this antenna need to be oriented relative to the wave in order to maximize its ability to detect the wave?

(c) Use Faraday's law to explain whether this antenna is a better detector for low-frequency waves or for high-frequency waves.
