All of the following are true of magnetic stimulation except:

In the context of magnetic stimulation, such as Transcranial Magnetic Stimulation (TMS), an electrical stimulator is not required to pace the stimulus. Instead, a magnetic coil is placed over the scalp, which generates a rapidly changing magnetic field. This magnetic field induces an electrical current in the underlying cortical neurons without direct electrical stimulation through wires. Therefore, the statement that an electrical stimulator is required for pacing is not accurate; the method relies on the magnetism rather than direct electrical pacing.

The other statements accurately describe aspects of magnetic stimulation. For instance, many people report that the stimulation does not cause significant pain, making it a preferable technique compared to other forms of stimulation, such as electrical stimulation, which can be uncomfortable. Additionally, the method relies on the basic principle of electromagnetism, wherein the coil of wire generates pulses of current, leading to the creation of a magnetic field. This magnetic field indeed causes movement in cortical neurons, enabling various applications, such as studying brain functions or providing therapeutic effects.
