Precautions to take when using strong magnetic fields

The ESR experiment (7.15) in the undergraduate laboratory makes use of a strong magnet. There is no evidence that exposure to the sort of fields generated by this magnet, even long-term exposure, is harmful. However, for obvious reasons it is wise to remove watches when inserting samples into the ESR magnet, and to keep credit cards and similar items away from the magnet.
