PROBLEM TO BE SOLVED: To provide a method and an apparatus for magnetic resonance detection capable of observing a signal having a high S/N ratio by reducing particular noise, such as external noise. SOLUTION: The apparatus for magnetic resonance detection has two resonance circuits having identical characteristics which are a sample resonance circuit 10 and a dummy resonance circuit 20. The sample resonance circuit 10 is arranged to guide a magnetic resonance signal and the dummy resonance circuit 20 is arranged not to guide the magnetic resonance signal. In addition, both the sample resonance circuit 10 and the dummy resonance circuit 20 are arranged so that they guide particular noise, such as external noise equivalently. A differential transformer 30 detects a differential signal from outputs of the sample resonance circuit 10 and the dummy resonance circuit 20, and the differential signal is detected as a magnetic resonance signal.
