Question
I need to know if these statements are ture or false or not, thank you!
A changed particle traveling opposite to a magnitude field does not experience a magnitude force. For any displacement of a changed particle, the work done by the magnitude force on the charged particle moving in a magnitude field is zero. An electric field makes a charged particle accelerate but a field takes it around in a circle. The magnetic field unlike the electric field is continues. A current carrying wire placed in a magnetic field perpendicular to the wire experience a maximum force. A wire carrying a current that placed in a magnetic field will experience a maximum force if the angle between the direction of the current and the direction of the magnetic field is 60 degree. A rectangular coil carrying a current in a magnetic field will experience a net torque that will cause the coil to rotate in that field, if the field is not along the coil axis. If two identical wires carrying a certain current in the same direction are placed parallel to each other, they will experience a force of repulsion. The magnetic field near a current carrying wire is directly proportional to the distance from the wire. The field near a long straight wire carrying a current is intensely proportional to the current flowing through the wire. The magnetic force on a circular loop of wire of radius r carrying current I around it is zero N. The magnitude of the magnetic field inside a solenoid is inversely proportional to the current following through the solenoid. There is no induced emf in a wire that is moving parallel to a magnetic field the wire is moving in the direction of the magnetic field. There is an induced emf in a wire that is moving parallel to a magnetic field if the wire is moving in the opposite direction to that of the magnetic field. An emf is induced in a wire by moving the wire near a magnet. An emf is induced in a wire by keeping a stationary magnet near the wire. An emf is induced in a wire by changing the current in that wire. An emf is induced in a wire by changing the current in a nearby wire. A changing magnetic flux through a closed loop of wire induces an emf in that loop.Explanation / Answer
