Question
1) A rectangular loop of wire is moving toward the bottom of the page with a speed of 0.20m/s The loop is leaving a region in which a magnetic field of 2.5 T is present during a time of t of 2.0s. What is the magnitude of ΔØ? 2) A charge of 10 μC travels with the speed of 10 x 10^6 m/s in a direction perpendicular to B and experience a force of 9 x 10^-3 N. What is the magnitude of the magnetic field B? 3) A straight wire in a magnetic field experiences a force of 0.03 N when the current in the wire is 2.7 A. What is the current in the wire when experiences a force of 0.05N? 4) A uniform magnetic field is directed east. A horizontal copper rod is perpendicular to the field and oriented in the north-south direction.The rod falls freely to Earth.a) What end of the rod becomes positive?b.) if the rod is initially oriented parallel to B,which end becomes positive (+)?
