Current some t24: currents at corners of squares-magnetic field at center t-carrying wires are positioned at the corners of a square. all of the currents have are into the page and some are out of the page. the same magnitude, but rank the magnitude of the net magnetic field at the center of the square. or all the samezero determine greatest all cannot east explain your reasoning. d3-rt25: pairs of long current-carrying wires-magnetic field nearby in these cases, the two parallel wires have the same magnitude current perpendicular to the plane of the page. the direction of the current in each wire is shown. rank the magnitude of the magnetic field at point p or all cannot zero determine all least- greatest explain your reasoning.
