The force on a current carrying wire is maximum only
when the wire is perpendicular to the direction of magnetic field
. It is minimum, that is, no force acts on the conductor when it is parallel to the magnetic field.
Under what condition does a force carry on a current carrying maximum?
The force experienced by a current-carrying conductor is the maximum
when the direction of current is perpendicular to the magnetic field’s direction
.
What is the force on a current carrying wire?
The force on a current-carrying wire in a magnetic field is
F = IlB sin θ
. Its direction is given by RHR-1.
Where is the magnetic force on a current carrying wire the strongest?
The magnetic field is strongest
in the area closest to the wire
, and its direction depends upon the direction of the current that produces the field, as illustrated in this interactive animation. Presented in the tutorial is a straight wire with a current flowing through it.
When the force experienced by a straight current carrying conductor will be maximum?
The force experienced by the current carrying conductors are placed in external magnetic field will be maximum when
the conductor is placed such that the direction of current is in it perpendicular to the direction of the magnetic field
.
Under what condition does current carrying conductor placed?
When the conductor is held
perpendicular to the magnetic field
, it experiences maximum force. Magnitude of this force depends on strength of magnetic field, orientation of the conductor, length of the conductor.
What are the factors that determine the size of the force on a current carrying conductor?
The magnitude of the force on a current carrying conductor
increases when the strength of the magnetic held is increased
. The magnitude of the magnetic force also depends on the length of the wire in the magnetic field. The longer the wire in the magnetic field, the larger the force on the wire as shown in Figure.
What is Fleming’s left hand rule?
Fleming’s left – hand rule states that
if we stretch the thumb, middle finger and the index finger of the left hand in such a
way that they make an angle of 90 degrees(Perpendicular to each other) and the conductor placed in the magnetic field experiences Magnetic force.
In which direction wire will move up or down?
Simply stated, the
Right
Hand Rule says that the magnetic field lines produced by a current-carrying wire will be oriented in the same direction as the curled fingers of a person’s right hand (in the “hitchhiking” position), with the thumb pointing in the direction of the current flow.
How does current affect magnetic field?
Current is
directly proportional to magnetic force
for a straight current carrying conductor in a uniform magnetic field. So the force is directly proportional to the size of the current. … If the current is increased by five times the force will also increase by five times.
What is the strength of magnetic field inside a long straight current carrying solenoid?
Answer: The strength of magnetic field inside a long current carrying straight solenoid is
the same at all points
.
What is the magnetic field inside a long straight solenoid carrying current?
The magnetic field inside a long straight solenoid-carrying current. is
zero
.
What happens to the force experienced by a current carrying conductor?
Whenever a current carrying conductor
is placed in a uniform magnetic field
. It will experience a magnetic force. When the current carrying wire is placed parallel or anti-parallel to the magnetic field, the magnetic field does not act on it.
What is the cause of magnetic field inside a human body?
The human body is a good conductor of electricity. Under the influence of an alternating current, the electric charges inside the body move back and forth at the same frequency as the field (60 Hz). In other words, the field produces
weak electric currents
in the body. … The body does not accumulate any current.
Which rule gives the direction of induced current?
FLEMING’S RIGHT HAND RULE
gives the direction of induced current in the conductor.
How can it be shown that magnetic field exist around a wire carrying current?
Answer:
By placing compass needle near current carrying wire
. If deflection in needle occurs,then it shows presence of magnetic field around wire.
