curves
closed loops
lines
Direction of magnetic field produced by a current carrying loop can be found by using
Fleming's Right hand rule
Clock Rule
Fleming's Left hand rule
Maxwell's corkscrew rule
Refer the diagram. A wire carries a current, creating a magnetic field around itself as shown. The current in the wire is:
Directed to the right
Directed to the left
Equal to the magnetic field
n the same direction as the magnetic field
Refer the diagram. The right face of the loop acts as North pole and left side of loop acts as south pole
False
True
Who was the first to observe the magnetic effect of electric current?
Faraday
Oersted
Volta
Ampere
Magnetic field inside a long solenoid carrying current is
same at all points (uniform)
different at poles and at the centre
zero
different at all points
The relative strength of the magnetic field is shown by the degree of closeness of the field lines.
false
true
can't say
No two field-lines are found to cross each other.
true
false
A wire is parallel to the lines of the force of the magnetic field and the current flows in the wire. Then
The wire will experience a force along the direction of the magnetic field
The wire will not experience any force
The wire will experience the torque
The wire will experience a perpendicular force
