Effect of injection or Suction and Magnetic Field on oscillatory flow in a planer channel

We investigated the oscillatory fluid dynamics of porous media defined by two horizontally parallel porous plates in the presence of transverse magnetic field. Both stationary plates receive the same constant injection / pumping speed (V). Graphical analysis of the effects of different parameters (injection / aspiration parameters, Darcy number, Hartmann number, oscillation frequency etc) on the velocity field and surface friction was obtained by obtaining analytical solution of closed form.

A magnetic field is a vector field that represents the magnetic effect of a current and a magnetized substance. In daily life, the influence of the magnetic field often occurs in a permanent magnet attracting magnetic material (such as iron) and attracting or repelling other magnets. The magnetic field surrounds and is generated by the magnetized material and the mobile charge (current) such as the charge used in the electromagnet. The magnetic field exerts a force on the moving charge nearby and the torque acts on the nearby magnet. In addition, the changing magnetic field with position exerts a force on the magnetic material. The strength and direction of the magnetic field are different depending on the position. Therefore, it is an example of a vector field.

Magnetism is basically a magnetic field, the influence it has on a substance, for example, the deflection of moving electric charge and the torque to other magnetic bodies. Evidence for the presence of a magnetic field is the magnetic force for the charge traveling in the magnetic field, the force being orthogonal to the charge and charge velocity of the magnetic field. This force diverts the particles without changing the velocity of the particles. Deflection is seen in the torque of the compass needle used to match the needle to the earth 's magnetic field. The needle is a thin part of iron magnetized, ie a small strip magnet. One end of the magnet is called the North Pole and the other end is called the South Pole. The force between the Arctic and Antarctic is attractive, and the force between similar poles is disgusting. The magnetic field is sometimes called magnetic induction or flux density and is always represented by B. The magnetic field is measured in Tesla (T)
