Q. What is the direction of the induced current when a magnet is moved towards a coil?
A.
Clockwise
B.
Counterclockwise
C.
No current
D.
Depends on the magnet's polarity
Solution
According to Lenz's law, the induced current will flow in a direction that opposes the change, which is counterclockwise if the magnet is moved towards the coil.
Q. What is the direction of the induced current when the magnetic field through a loop is increasing?
A.
Clockwise
B.
Counterclockwise
C.
No current
D.
Depends on the field strength
Solution
According to Lenz's law, the induced current will flow in a direction that opposes the change in magnetic flux. If the magnetic field is increasing, the induced current will flow counterclockwise.
Q. What is the direction of the induced current when the magnetic field through a loop decreases?
A.
Clockwise
B.
Counterclockwise
C.
No current
D.
Depends on the field strength
Solution
According to Lenz's law, the induced current will flow in a direction that opposes the change, so it will be counterclockwise if the magnetic field decreases.
Q. What is the direction of the magnetic field around a current-carrying conductor? (2019)
A.
From North to South
B.
From South to North
C.
Clockwise
D.
Counterclockwise
Solution
The direction of the magnetic field around a current-carrying conductor is given by the right-hand rule, which indicates a counterclockwise direction when viewed from the positive current side.
Q. What is the direction of the magnetic field around a current-carrying wire as per the right-hand rule?
A.
Clockwise
B.
Counterclockwise
C.
Radial
D.
Tangential
Solution
According to the right-hand rule, if you point your thumb in the direction of the current, your fingers curl in the direction of the magnetic field lines, which is counterclockwise.
Q. What is the direction of the magnetic field around a current-carrying wire?
A.
Radially inward
B.
Radially outward
C.
Clockwise or counterclockwise depending on current direction
D.
Perpendicular to the wire
Solution
The direction of the magnetic field around a current-carrying wire is determined by the right-hand rule, which gives a clockwise or counterclockwise direction based on the current's direction.
Correct Answer:
C
— Clockwise or counterclockwise depending on current direction
Q. What is the direction of the magnetic field around a straight conductor carrying current, as per the right-hand rule?
A.
Clockwise
B.
Counterclockwise
C.
Radially inward
D.
Radially outward
Solution
Using the right-hand rule, if you point your thumb in the direction of the current, your fingers curl in the direction of the magnetic field, which is counterclockwise.
Q. What is the direction of the magnetic field around a straight conductor carrying current? (2023)
A.
From north to south
B.
Clockwise
C.
Counterclockwise
D.
Radially outward
Solution
The direction of the magnetic field around a straight conductor carrying current is counterclockwise when viewed from the positive end of the conductor.
Q. What is the direction of the magnetic field around a straight current-carrying conductor?
A.
From north to south
B.
From south to north
C.
Clockwise
D.
Counterclockwise
Solution
The direction of the magnetic field around a straight current-carrying conductor can be determined using the right-hand rule, which indicates that the field lines form concentric circles around the conductor in a counterclockwise direction when viewed from the positive end.
Q. What is the direction of the magnetic field due to a current flowing in a circular loop when viewed from above? (2023)
A.
Out of the plane
B.
Into the plane
C.
Clockwise
D.
Counterclockwise
Solution
Using the right-hand rule, if the current flows in a counterclockwise direction when viewed from above, the magnetic field direction is out of the plane.
Q. What is the direction of the magnetic field inside a long straight current-carrying conductor?
A.
Outward from the conductor
B.
Inward towards the conductor
C.
Circular around the conductor
D.
No magnetic field present
Solution
According to the right-hand rule, the magnetic field lines around a straight conductor carrying current are circular and lie in planes perpendicular to the conductor.
