Some pacemakers employ magnetic reed switches to enable doctors to change their mode of operation without surgery. A typical reed switch can be switched from one position to another with a magnetic field of 5.0x10-4T. What current must a wire carry if it is to produce a 5.0x10-4T field at a distance of 0.50 m?
