Figure P30.17 shows a magnetic field line pattern radiating from an oscillating electric dipole.

(a) What is the direction of the change, over the next infinitesimal time interval, in the magnetic field at P?

(b) Use your answer to part \(a\) to determine the direction of the electric field loop around P.

(c) Is the dipole oscillating right-left, updown, or in-out of the page?
