Anyone who remembers high-school physics knows that a fluctuating magnetic field can induce an electrical current. That's the principle behind transcranial magnetic stimulation (TMS), where an electromagnet is held over the head and pulsed rapidly. Depending on the frequency of the pulses, this can either enhance or suppress activity in neurons a few centimetres under the skull.

TMS is seen as one of the safer forms of brain stimulation, as it requires no surgery. Yet it is not completely risk free: some people experience pain in the scalp, headaches or facial spasms. More concerning were the 10 cases of seizures triggered by TMS in the first few years of its use.
