Magnetic Fields Assignment 1) You are given the following diagram showing the deflection paths of charged particles entering a magnetic field at right angles. Identify which path is an electron (e), a proton (p), an alpha particle (a )and a neutron (n ) by placing the symbols beside the path. (4) Magnetic Field Direction I II III IV V 2) You are given the following experimental set-up. A 20.0 V battery is attached to a conducting cable in a magnetic field, as shown. The supplied power is also 18.0 W, the cable length is 10.0 em and the magnetic field strength is 0.510 T. Calculate the force on the cable. (3) N S 3) The energy of a proton is 894 eV. It enters a magnetic field and its resulting circular path has a radius of 36.0 mm. An alpha particle later enters the same magnetic field with the same velocity. a) Find the speed of the proton upon entering the magnetic field. (3) b) Find the magnitude of the magnetic field strength. (8) c) Determine the radius of the alpha particle's path in the same magnetic field. Mathematically compare it to the radius of the proton
