Magnetite is a Grayish black/ Iron black metal with a non-fluorescent texture. It is a naturally strong magnetic in nature and Its density ranges from 5.1- 5.2.
The lines of force are closest together at the poles of a bar magnet. As they approach the poles, the magnetic field becomes more concentrated and the lines of force crowd together, displaying greater density.
The lines around a bar magnet represent the magnetic field. They indicate the direction in which a magnetic north pole would move if placed in the field. The density of the lines indicates the strength of the magnetic field.
The magnetic field is strongest at the poles of a bar magnet.
A bar magnet attracts a paper clip with more force compared to a refrigerator magnet because the magnetic field of the bar magnet is stronger due to its design and material composition. The shape and alignment of the magnetic domains in a bar magnet allow for a more concentrated and powerful magnetic field, resulting in a stronger pull on the paper clip.
To demagnetize a bar magnet using a solenoid, the magnet can be placed inside a solenoid and the current can be gradually decreased to zero. This process disrupts the alignment of magnetic domains within the magnet, leading to demagnetization. The alternating current can also be used for more effective demagnetization.
The strength of a magnet can be determined by measuring its flux density (B) which is expressed in teslas. The flux density will vary according to where relative to the magnet it is being measured. The instrument for doing this is a flux-density meter (which was called a 'gaussmeter' - 'gauss' being an obsolete unit of measurement for flux density, from the cgsA metric system).
They are bar magnet ,horse shoe magnet ,lime stone magnet.
The lines of force are closest together at the poles of a bar magnet. As they approach the poles, the magnetic field becomes more concentrated and the lines of force crowd together, displaying greater density.
no
Move towards the U magnet so that the poles attach.
The magnet bar is used for stirring solutions.
a electromagnet is bigger than a bar magnet
Yes, a bar magnet is magnetic.
The lines around a bar magnet represent the magnetic field. They indicate the direction in which a magnetic north pole would move if placed in the field. The density of the lines indicates the strength of the magnetic field.
because it is easy to convey from small bar magnet
The magnetic field is strongest at the poles of a bar magnet.
Yes, a bar magnet is inherently magnetic due to its alignment of magnetic domains within the material. This alignment creates a magnetic field around the magnet that interacts with other magnetic material or objects.
