1. A device for generating a time-varying magnetic field and causing a muscle of a patient to contract, comprising:

  • a magnetic field generating coil configured to generate a time-varying magnetic field;

    a first applicator comprising the magnetic field generating coil, wherein the first applicator is configured to be placed in contact with a patient'"'"'s skin or clothing at a body region of the patient, and wherein the body region comprises an abdomen or a buttock; and

    a belt configured to position the first applicator in contact with the patient'"'"'s skin or clothing at the body region;

    wherein the device is configured such that the time-varying magnetic field generated by the magnetic field generating coil comprises a magnetic flux density of 0.5 Tesla to 7 Tesla at a surface of the magnetic field generating coil and a maximal value of a magnetic flux density derivative in a range of 300 T/s to 800 kT/s,wherein the device is configured such that the time-varying magnetic field is applied by the first applicator to muscle fibers, neuromuscular plates, or nerves innervating muscle fibers in the body region to cause a supramaximal contraction of the patient'"'"'s muscle in the body region, andwherein the device is configured to apply magnetic pulses with a repetition rate in a range of 1 Hz to 300 Hz in at least two trains, each train causing a supramaximal contraction of the patient'"'"'s muscle, wherein each train lasts between 1 second and 30 seconds, and wherein a time between two subsequent trains lasts between 1 second and 30 seconds.
