A set of circuit is developed to receive electromagnetic waves used in the teaching of electromagnetic fields and waves. The circuit has the characteristics of easy building and low cost. It can help students understand the procedure of the radiation and receiving of electromagnetic waves, and get whole knowledge of the rule of electromagnetic induction. The electromagnetic oven and the electric hairdyer are adopted as radiators with low radiation frequency and power, and little harm to the experiment participators.
