Knex Ampere Force refers to the force exerted on the electrified wire in the magnetic field. The ampere force exerted on a wire of any shape in a uniform magnetic field can be regarded as the vector sum of the ampere force exerted on an infinite number of linear current elements in the magnetic field. Here you only need to input three key data information to get the remaining data values, which is convenient for research tests, greatly improves efficiency and facilitates better research topics.
