1. For each of the following, say whether it is "A"Iways true, "S"ometimes true or "N"ever true. NIf the highest occupied band of a solid is partially filled, it will be an insulator. AIfa charged particle moves clockwise in a plane, the magnetic field it produces is into the plane. Suppose two solenoids receive exactly the same amount of current. If the second solenoid has more turns, it will produce a higher magnetic field inside the coil. A Suppose only one battery is in a complete circuit initially. If a second battery is connected in series with the first battery, the current will increase. ALong parallel currents in opposite directions attract each otherExplanation / Answer
Suppose two solenoids receive exactly the same amount of current. If the second solenoid has more turns, it will produce a higher magnetic field inside the coil.
ANSWER: A
As the number of turns increases, the inductance value gets higher. Since, magnetic field is directly proportional to the inductance, it also gets higher.
Suppose only one battery is in a complete circuit initially. If a second battery is conected in series with the first battery, the current will increase.
ANSWER: N
When the batteries are connected in series, the voltage is additive while the current remains the same. There is no change in the current.
Long parallel currents in opposite direction attract each other.
ANSWER: N
If two identical wires carrying a certain current in the opposite direction, are placed parallel to each other, they wil experience a force of repulsion.
