A wire carrying a current is wound into a tight, loop shaped coil Problem: 2.2-m-long 3.5 A 5.0 cm in diameter. What is the magnetic field at its center? Magnetic field due to a steady current in a long straight wire: Problem: In standard household wiring, wires about apart carry parallel currents of about What is 2 cm 60 A. the magnitude of the force per unit length between such wires?
Problem: A 2.2-m-long wire carrying a 3.5 A current is wound into a tight, loop shaped coil 5.0 cm in diameter. What is the magnetic field at its center? Magnetic field due to a steady current in a long straight wire: Problem: In standard household wiring, wires about 2 cm apart carry parallel currents of about 60 A. What is the magnitude of the force per unit length between such wires?
