1 peints Save Answer Along staight wire carried by a cument of 4.7 A is placed in a magnetic field and the magnitude of magnetic force is 0.029 N The magnetic field and the length of the wow are remained unchanged. The magnetic force acting on the wire is changed to 0.011 N while the current is changed to a different value What is the value of this changed cument? (Give your answer in amps but don't include the units)
