The magnetic field is strongest
inside the coil of
a solenoid.
Where is the magnetic field weakest in a solenoid?
It is equally strong at the north pole when compared with the south pole. The force is weaker in
the middle of the magnet and halfway between the pole and the center
.
Why is the magnetic field inside a solenoid stronger?
The field inside a solenoid is strong and uniform. The
small magnetic fields caused by the current in each turn of the coil add together to
make a stronger overall magnetic field.
Where is the field strongest in the magnetic field?
The magnetic field is strongest
at the center
and weakest between the two poles just outside the bar magnet. The magnetic field lines are least dense at the center and densest between the two poles just outside the bar magnet.
What is the magnetic field strength inside the solenoid?
The magnetic field inside a solenoid is
proportional to both the applied current and the number of turns per unit length
. There is no dependence on the diameter of the solenoid, and the field strength doesn’t depend on the position inside the solenoid, i.e., the field inside is constant.
How do you find the magnitude of the magnetic field inside the solenoid?
We assess the magnitude of the magnetic B-filed by using Ampère’s law:
∫l→B⋅d→l=μoIc
. We use a rectangle denoted ABCD as the Ampère’s curve, with two sides of length h parallel to the axis of the solenoid.
Which refers to the end of a magnet where the forces are strongest?
Magnetic Pole
. The ends of a magnetic object, where the magnetic force is strongest.
Where is a magnetic field around a wire 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.
How can the strength of a solenoid be increased?
Strength of the magnetic field in solenoid can be increased by:
increasing the current in the coil. increasing the number of coils in the solenoid
; and. using a soft iron core within the solenoid.
Is strength of magnetic field same at all points inside a solenoid?
Yes
, The strength of a magnetic field is same at all points inside a solenoid.
Where is the magnetic field the strongest on poles?
The magnetic field is strongest at
the poles
, where the field lines are most concentrated. Field lines also show what happens to the magnetic fields of two magnets during attraction or repulsion.
Where the magnetic field is uniform in solenoid?
A solenoid is a tightly wound helical coil of wire whose diameter is small compared to its length. The magnetic field generated
in the centre, or core
, of a current carrying solenoid is essentially uniform, and is directed along the axis of the solenoid.
Where is the magnetic field the strongest and why?
the magnetic field lines never cross each other. the closer the lines, the stronger the magnetic field (so the magnetic field from a bar magnet is strongest
closest to the poles
)
Where do you think the field strength of a current carrying solenoid will be maximum Why?
Look as the field strength is maximum
at the inside part of a solenoid
as the number of field lines are very dense and the field at the outside is minimum as the field lines are less dense outside the solenoid .
How magnetic field is produced in the solenoid?
when electric current is passed through solenoid it produces magnetic field
. Solenoid are important bcoz they can create controlled magnetic fields and can be used as electromagnet.
How do you measure the strength of a magnetic field?
A current I through a long, straight wire produces a magnetic field with strength
H=I/2πr at
a distance r from the wire. So the field strength is inversely proportional to the distance from the wire.
What is the magnitude of the magnetic field?
The SI unit for magnitude of the magnetic field strength is called the tesla (T), which is equivalent to
one Newton per ampere-meter
.
Which shape of magnet is the strongest?
The strongest part of a magnet is concentrated at the poles. That is why
a horseshoe shape
is considered the strongest and can be very useful to create if you want to lift heavy objects or want to make a bar magnet stronger.
Where is the magnetic strength of a magnet concentrated?
Answer: Magnetic strength of a magnet is concentrated at the two regions namely
the poles of the magnet
.
Which type of magnet is strongest?
Neodymium magnets
are by far the strongest type of permanent magnet available.
Is there magnetic field outside a solenoid?
The magnetic field lines follow the longitudinal path of the solenoid inside, so they
must go in the opposite direction outside of the solenoid
so that the lines can form a loop. … In order for the total number of field lines to be conserved, the field outside must go to zero as the solenoid gets longer.
Where is the magnetic field due to straight current wire stronger weaker?
In general, the magnetic field is strongest
close to the wire and weaker farther away
. In fact, the magnetic field weakens as where is the distance from the wire. This can change a bit depending on the length and shape of the wire.
How does the strength of the magnetic field depend on the current?
The magnetic field is caused by the current flowing in the wire.
The bigger the current the stronger the magnetic field
and hence the stronger the electromagnet.
What are the factors that affect the strength of the magnetic field in a solenoid?
Factors Affecting the Strength of the Magnetic Field of an Electromagnet: Factors that affect the strength of electromagnets are
the nature of the core material, strength of the current passing through the core, the number of turns of wire on the core and the shape and size of the core
.
How the strength of magnetic field in a current carrying solenoid will change if the number of turns in it will increase?
(i) Number of turns in the solenoid: The larger the number of turns in the solenoid,
stronger is the magnetic field produced
. (ii) Strength of the current: Greater the current passed through the solenoid, stronger is the magnetic field produced.
How can the strength of the magnetic field at a given distance from the wire be increased?
The force on a given length of wire in a magnetic field increases when:
the current in the wire increases
. the strength of the magnetic field increases. the length of conductor in the field is increased.
Where is the magnetic field uniform?
A uniform magnetic field is a circumstance where
the magnetic field lines are moving from North to the South Pole of a magnet with a uniform severance
and they are peripatetic in a straight line, this is not probable to acquire with a single stable magnet.
Where is the current maximum in a solenoid?
A solenoid carrying current has (i) maximum value of magnetic field at a point will
inside the solenoid lying on the axis of solenoid
. (ii) There is a minimum value of magnetic field at a point outside the solenoid near the middle of solenoid and (iii) half of the maximum value at a point near the end of the solenoid.
Where is the magnetic field of a current element is minimum and II maximum?
(i) The magnetic field of a current element is minimum (which is zero) along the axis of a current element. (ii) The magnetic field of a current element is maximum in
a plane passing through the element and perpendicular to its axis
.
Where is the strength of the magnetic field the i highest II same at all points in a current carrying solenoid?
The magnetic field lines inside a current carrying solenoid are parallel and equidistant which means the strength of magnetic field is uniform
inside the solenoid
i.e. same at all points.
Where is the force of magnetic lines strongest in a bar magnet?
The magnetic field is strongest
at the center
and weakest between the two poles just outside the bar magnet. The magnetic field lines are least dense at the center and densest between the two poles just outside the bar magnet.
What is solenoid draw the magnetic field lines inside and outside the current carrying solenoid?
A solenoid is a coil of a large number of circular turns of wire wrapped in the shape of a cylinder. On passing electric current, a magnetic field is developed along the
axis of solenoid
. Magnetic field lines are drawn above. … While there is no field emanating from the lateral surface of the solenoid.
