Explanation:
As we know that magnetic field due to torroid is given as
this is approximately constant magnetic field along the axis of the torroid
now the flux linked with one coil of the torroid is given as
now total flux of N number of coils is given as
now we know that self inductance is the property of coil in which flux of the coil will link with the current in the coil
So we know that
The force exerted by a magnetic field on a wire carrying current is:
where I is the current, L the length of the wire, B the magnetic field intensity, and
the angle between the wire and the direction of B.
In our problem, the force is F=0.20 N. The current is I=1.40 A, while the length of the wire is L=35.0 cm=0.35 m. The angle between the wire and the magnetic field is
, so we can re-arrange the formula and substitute the numbers to find B:
where I is the current, L the length of the wire, B the magnetic field intensity, and
In our problem, the force is F=0.20 N. The current is I=1.40 A, while the length of the wire is L=35.0 cm=0.35 m. The angle between the wire and the magnetic field is
The equivalent of the Newton's second law for rotational motions is:
where
is the net torque acting on the object
is its moment of inertia
is the angular acceleration of the object.
Re-arranging the formula, we get
and since we know the net torque acting on the (vase+potter's wheel) system,
, and its angular acceleration, 
, we can calculate the moment of inertia of the system:
where
Re-arranging the formula, we get
and since we know the net torque acting on the (vase+potter's wheel) system,
