The magnitude of the magnetic field at the center of a 33-turn loop of wire is 1.7 x 10-T Calculate the current in the loop if the radius is 29 cm. Give your answer in amps but don't include the units)
A long staight wire carried by a current of 3.3 A is placed in a magnetic field and the magnitude of magnetic force is 0.013 N. The magnetic field and the length of the w unchanged. The magnetic force acting on the wire is changed to 0.023 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) 1 points Save A Tamarad
MUNDUR m Save an A 35-turn circular loop of wire is placed into a magnetic field with initial magnitude 2.9 T. The magnetic field is perpendicular to the surface of the loop Over a period of 085 second the strength of the field is decreased to 1.4T and as the field decreases a 3.5 V emf is induced in the loop. Calculate the diameter of the loop of wire (Give your answer in meters but don't include the units)
