Answer and Explanation: The magnetic field is strongest inside the coil of a solenoid. Inside the coil of a solenoid the magnetic field lines are uniform and tightly packed together which creates a stronger magnetic field here than anywhere outside of the solenoid.
The net magnetic field is the sum from each individual loop and is maximum in the middle of the solenoid because that point minimizes the average distance to each loop. At the end of the solenoid the average distance to all the loops is greater, hence the magnetic field is less.
Strength of a Solenoid
Adding more turns to the coil of wire increases the strength of the field. Increasing the amount of current flowing through the coil also increases the strength of the magnetic field.
The strength of the magnetic field of a solenoid increases with the increase of strength of electric current in the solenoid. The strength of the magnetic field is directly proportional to the amount of current passing through the current carrying conductor. More the current, more the strength of the magnetic field.
1. The number of turns in the solenoid: If the number of turns in the solenoid is large, they will produce a greater magnetic field produced (magnetism). 2. The strength of current in the solenoid: If the current passing through the solenoid is larger, stronger will be the magnetic field produced (magnetism).
The strength of the magnetic field depends upon the number of turns in the solenoid, strength of the current and the nature of the core-material used in making solenoid. Larger the current passed , stronger will be the magnetic field produced in the solenoid.
Standard lifting solenoids can exert a lifting force of up to 650 N.
The magnetic lines of the magnetic field are stronger at the poles than at the middle part in case of both the bar magnet and the solenoid.
Current in solenoid produces a stronger magnetic field inside the solenoid than outside. The field lines in this region are parallel and closely spaced showing the field is highly uniform in strength and direction. That's why the magnetic field inside the solenoid is stronger than outside.
Solenoid coil failure can be caused by a number of factors. Applying an incorrect voltage to the coil will cause it to fail and may cause the coil to burn out. Electrical surges or spikes may also damage the coil. Burnt out coils cannot be repaired and will need to be replaced.
As the soft iron core is a highly ferromagnetic material, It allows (and attracts) the magnetic field lines to pass through it. When such material is used in the electromagnet, the magnetic field lines passing through it increases, thereby, the strength of the electromagnet increases.
The magnetic field within a solenoid depends upon the current and density of turns. The energy density of the magnetic field depends on the strength of the field, squared, and also upon the magnetic permeability of the material it fills. Iron has a much, much larger permeability than a vacuum.
The magnetic field is weakest at the center and strongest between the two poles just outside the bar magnet. The magnetic field lines are densest at the center and least dense between the two poles just outside the bar magnet.
The magnetic field around a magnet is the strongest at the poles. The maximum number of magnetic field lines pass through the poles.
The north and south poles of a magnet are equally strong. The strength of a magnet refers to the ability of the magnet to produce a magnetic field and to attract or repel other magnets or magnetic materials. A magnet's strength is independent of its magnetic pole.
The closer the magnetic field lines are, the stronger the magnetic field at that point. As we can see in the diagram, the magnetic field lines are closer or denser at the poles. So, the magnetic field is strongest around the poles of the magnet.
If the magnetic field lines are very close to each other in a particular region, then the magnetic field is said to be strong. If the magnetic field lines are far away from each other in a particular region, then the magnetic field is said to be weak.
The strength of a solenoid can be increased by increasing the number of turns. The magnetic field due to a solenoid is similar to the magnetic field produced by a bar magnet.
While the majority of solenoids are designed to pull, a simple design change can allow them to push. The only modification necessary is to extend the internal end of the plunger with a pushrod.
Solenoid coils are rated to operate from 12-V to 24-V DC and 110-V to 230-V AC systems with a power consumption ranging from 8 to 20 W.
The strength of a current-carrying solenoid decreases with a rise in its temperature. Concept Used: The magnetic field and dependence on temperature.
Answer: Maximum inside the coil of solenoid and minimum at the end of solenoid .
The radius and the length don't directly affect the field, they affect indirectly the ampere turns . Larger the outer diameter and greater the length of the solenoid, more turns of the conductor can be accommodated. But this will increase the resistance of the coil.
