True.
Magnetic Disks, otherwise known as 'Floppy disks'. The last generation of these disks were 3 1/2" and used a ridgid plastic case, to contain the magnetic disk within. Not very floppy. The early versions were 7" and 5" and were contained in soft plastic outer sleeves. These were actually floppy.
Yes, data is written to and read from a floppy disk using a magnetic read/write head that interacts with the magnetic coating on the disk. When writing data, the magnetic head aligns the magnetic particles on the disk surface to represent the information. When reading data, the head detects the magnetic orientation of the particles to retrieve the stored information.
The spinning proton magnetic field influences the behavior of particles in a magnetic field by aligning with or against the external magnetic field. This alignment affects the energy levels of the particles, leading to phenomena like nuclear magnetic resonance and the Zeeman effect.
It is the magnetic elements in a magnetic disk that are used to store information.
You can separate magnetic and nonmagnetic particles using a magnet. The magnetic particles will be attracted to the magnet and can be easily separated from the nonmagnetic particles. This method is commonly used in industries such as mining and recycling.
Magnetic separation is technique used in metallurgyfor the concentration of ore particles. The principle of this method is that the magnetic ore particles can be separated from non magnetic impurities (gangue) or viceversa.
The magnetic strip on ATM cards is made of magnetic material that stores account information in binary code. It is typically made of a polymer material with magnetic particles embedded in it. The strip is encoded with data that can be read by magnetic stripe readers to authorize transactions.
The magnetic field variable affects the behavior of charged particles in a magnetic field by exerting a force on them. This force causes the charged particles to move in a curved path perpendicular to both the magnetic field and the direction of their initial velocity.
if charge particle is in motion ,then it has magnetic field
No, a static magnetic field cannot do positive work on charged particles. Magnetic fields can only do work on moving charged particles by changing their directions of motion or causing them to spiral. Static magnetic fields do not affect stationary charged particles.
A magnetic field can exist without current due to the intrinsic magnetic properties of particles like electrons. In atoms and materials, the alignment of these particles' spins can create a magnetic field. This is known as magnetism and is responsible for phenomena like the Earth's magnetic field.
