To learn to apply the concept of current density and microscopic Ohm's law. A "gauge 8" jumper cable has a diameter ddd of 0.326 centimeters. The cable carries a current III of 30.0 amperes. The electric field EEE in the cable is 0.062 newtons per coulomb. Part APart complete Part B What electric field E′E′E' would have been required to create a current of 30.0 amperes in a copper "gauge 10" wire with diameter ddd equal to 0.259 centimeters?

Aloop of wire is in a magnetic field such that its axis is parallel with the field direction. which of the following would result in an induced emf in the loop? choose all that apply. a loop of wire is in a magnetic field such that its axis is parallel with the field direction. which of the following would result in an induced emf in the loop? choose all that apply. moving the loop outside of the magnetic field region. spin the loop such that its axis does not consistently line up with the magnetic field direction. change the magnitude of the magnetic field. change the diameter of the loop
