The electrostatic potential satisfies Laplace’s equation in any region free of charges. Also the heat equation (Sec. 12.5) reduces to Laplace’s equation if the temperature u is time-independent ("steady-state case"). Using (20), find the potential (equivalently: the steady-state temperature) in the disk if the boundary values are (sketch them, to see what is going on)

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
