Magnet , around for ferrite and SmCo, about for NIB and lower for flexible ceramics, but the exact numbers depend on the grade of material. An electromagnet, in its simplest form, is a wire that has been coiled into one or more loops, known as a solenoid. When electric current flows through the wire, a magnetic field is generated. It is concentrated near (and especially inside) the coil, and its field lines are very similar to those of a magnet. The orientation of this effective magnet is determined by the right hand rule. The magnetic moment and the magnetic field of
High-Intensity Focused Electromagnetic Field muscle contractions due to the action potential. The exposure of muscles to these contractions leads to muscle strengthening. In aesthetic medicine, HIFEM is used as a non-invasive body contouring treatment for abdomen and buttocks. The same technology is used in urology and gynecology to treat urinary incontinence through strengthening of the pelvic floor muscles. A pulse of electric current flowing through a wire coil generates a rapidly changing magnetic field. The changing magnetic field induces a secondary electric current in the nearby tissue. When applied on peripheral level the secondary electrical current depolarizes neural membranes of underlying neurons. Motor neurons
