Moving Charges and Magnetism
Very Short Q & A
Q1: Define Magnetic Field.
Answer: The space around a magnet within which its effect is experienced is called Magnetic Field (B).
Q2: What is the SI unit of magnetic field?
Answer: Tesla. Another unit is Newton Ampere-1 metre-1
Q3: What is a solenoid?
Answer: A solenoid is a circular coil of a large number of turns, such that the turns of solenoid run parallel to its length. It acts similar to a bar magnet.
Q4: What is Lorentz force?
Answer: The total force on a charge (q) moving with a velocity (v) in the presence of magnetic and electric field (B and F) respectively is called Lorentz force.
Q5: What is a cyclotron?
Answer: It is a machine to accelerate charged particles or ions to high energies
Q6: What is the operational definition of one ampere?
