(1 poi Which of the following statements is NOT true? Select the correct answer O At a perpendicular distance of 6 meters away from a long straight wire the magnitude of the magnetic field is half that at a distance of 3 meters O The magnitude of the magnetic field produced by a long straight wire at a certain distance r from the wire depends on the direction that positive current flows through the wire The direction of the magnetic field produced by a long straight wire can be determined using a right hand rule in which you point O your thumb in the direction of positive current O Select this answer if all of the statements are true The formula for the magnitude of the magnetic field produced by a long straight wire with current is derived from the more general Biot-Savart Law
