The
magnetic field lines
are concentric circles at every point of a current carrying circular loop. The direction of magnetic field of every section of the circular loop can be found by using the right hand thumb rule. At the centre of the circular loop, The magnetic field lines are straight.
What form of magnetic field lines are produced by a circular current carrying coil?
At the centre of circular wire,field lines
become straight and perpendicular to the plane
of coil. Right hand thumb rule is used to determine the direction of magnetic field produced due to current carrying circular wire.
When magnetic field lines are drawn around a current carrying circular loop it has?
When magnetic field lines are drawn around a current carrying circular loop, it has been observed that
they are closed tc its axis
. But these lines keeps on diverging as we move away from the centre.
What field circles a current carrying wire?
Magnetic Field
of Current
The magnetic field lines around a long wire which carries an electric current form concentric circles around the wire.
What kind of magnetic field is produced by a current carrying circular coil show it with the help of Labelled diagram?
The magnetic field pattern due to a circular coil is as shown in the given figure. At every point of current carrying circular loop, the concentric circles representing the magnetic field around it becomes larger and larger as we move away from the wire. At the center of the loop, the field appears as a straight line.
Where is the magnetic field inside a current carrying circular conductor strongest?
In case of circular loop, magnetic lines of force are highly concentrated
at centre
as shown in figure. so, magnetic field is strong at centre . While in case of circumference , magnetic field is weaker than centre.
What will be the magnetic field value at the center of a current carrying coil?
Magnetic Field at the Center of a Circular Current-Carrying Coil.
dB = μ 0 4 π Id l sin θ r 2
where is the angle between d l → and .
Why do magnetic field lines keep on diverging as we move away from the Centre of current carrying circular loop?
Answer: We know that
the magnetic field is stronger near the current carrying conductor and decreases as
we move away from the conductor. … As we move towards the periphery of the circular loop, the magnetic field lines appear to be diverging so that they can be circular around the wire of the loop.
What are the two properties of magnetic field lines?
- The field is tangent to the magnetic field line.
- Field strength is proportional to the line density.
- Field lines cannot cross.
- Field lines are continuous loops.
How do you increase the magnetic field of a solenoid?
- increasing the number of turns on the coil.
- increasing the current.
- placing an iron core inside the solenoid.
What is the shape of the magnetic field lines around a long straight current carrying wire?
The Magnetic field lines around a straight conductor carrying current are
concentric circles
whose centres lie on the wire. The direction of magnetic field lines can be determined using Right-Hand Thumb Rule.
What shape does the magnetic field around a current carrying wire form?
When a current flows in a wire, it creates a
circular
magnetic field around the wire. This magnetic field can deflect the needle of a magnetic compass.
What are the factors on which the magnetic field due to a current carrying circular coil depends?
- The current passing through the circular loop-directly proportional.
- The radius of circular loop-inversely proportional.
- Number of turns of the wire in the circular loop-directly proportional.
What is solenoid with diagram?
The solenoid is a device with a long cylindrical coil of wire having a large number of turns fixed together very tightly. … The condition for being a solenoid is that the length of the coil must be greater than its diameter. The magnetic
field
around a current carrying solenoid is represented in the diagram.
What is the magnitude and direction of the magnetic field inside a current carrying solenoid?
B = mu(o) n I
For direction of Magnetic field, we can use Right hand thumb rule.
