A Long Staight Wire Carried By A Current Of 4 7 A Is Placed In A Magnetic Field And The Magnitude Of Magnetic Force Is 0 2 (58.05 KiB) Viewed 20 times
A long staight wire carried by a current 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 wire 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 current? (Give your answer in amps but don't include the units.)
