On which factors does the magnetic field at the center of a coil depend? Select 3. The radius of the coil. The resistance of the coil. The amount of current in the coil. The type of wire used in the coil. The number of turns of wire in the coil. 6. INDUCED MAGNETIC FIELD OF A COIL A circular coil is made with the following parameters: number of turns of wire =590 radius =0.25 m current =9.9 A A. What is the magnetic field strength at the center of the coil? Bcenter = B. What is the magnetic field strength along the axis of the coil a distance of 0.4 m from the center? Baxis=
