What is the magnetic field at the point o?
The earth’s magnetic field at the place is 0.
How will Magnetic field strength at the center of the circular current loop change if the current through the coil is halved and radius of the loop is doubled?
Answer: At the center of a current carrying coil, the magnetic field intensity is directly proportional to the current and inversely proportional to the radius of the coil. So, if the current is doubled and radius is halved, then the value of B increases by 4 times the initial value.
At which point on the axis of the circular coil carrying current the magnetic field is maximum?
Assertion(A) : For a point on the axis of a circular coil carrying current ,magnetic field is maximum at the centre of the coil. Reason(R) : Magnetic field is inversely proportional to the distance from the circular coil.
How will the magnetic field intensity at the center of circular coil carrying current change if the current through the coil is doubled and radius of coil is halved?
Answer. At the center of a current carrying coil, the magnetic field intensity is directly proportional to the current and inversely proportional to the radius of the coil. So, if the current is doubled and radius is halved, then the value of B increases by 4 times the initial value.
What happens to the magnetic field at the Centre of a circular current carrying coil if we double the radius of the coil?
On doubling the radius, magnetic field reduces to half.
How does the strength of the magnetic field at the Centre of the circular coil of wire depends on?
The strength of magnetic field depends upon: (i) Magnetic field(B) is inversely proportional to the radius of the coil. (ii) B is directly proportional to the number of turns n of the coil. For each circular turn, the direction of current is same.
What will happen to magnetic field at the center of current carrying loop if I the radius of loop is halved II current is double III number of turns are doubled IV the direction of electric current is reversed?
Answer. Biot Savrat Law affects the strength of magnetic field induced due to current flowing through the loop. Explanation: (1)When the loop’s radius is decreased as magnetic field strength formula is inversely proportional to radius of the loop, becomes double of the magnetic field strength.
How will Magnetic Field be produced in a current carrying circular coil change if I decrease the value of current II number of turns increase III radius doubled?
When we increase the distance from the coil, the magnetic field produced by a current carrying circular coil decreases. So if we increase the number of turns of the coil, more current will pass through the wire which indicates that the magnetic field associated with it also increases.
