3.3 in the coil a circle with electric currents, magnetic fields have occurred surrounding it and a magnetic field in the loop will have the value makkwan the chest circumference. Value of the magnetic field at the Center write a formula that. When k ' = 10-7 ampere-meter I cam Gerber/, B & r is Ali current, magnetic fields, and the radius of a circle, respectively. Thou shalt find the magnetic coil center point circle radius 2 m with currents flowing through 10 ampere.
