What is the difference between a permanent magnet and a temporary magnet

Physics

Flura [38]3 years ago

A permanent magnet does not loose its magnetism easily. It can only be lost by permanent destruction say by fire. Example of this is magnetism from a bar magnet. This magnetism is not induced by say electric current.

A temporary magnet looses its magnetism easily. The magnetism is gained or loosed for the action of carrying out a particular task. This magnetism can be achieved by the gain or loss by passing of electric current over say an iron core.

Optics of the eye: the closest object that a typical young person with normal vision can focus on clearly is closest to:______.
Natali [406]

The human eye is one of the most valuable sense organ. The closest object that a typical young person with normal vision can focus closest to is 25 cm

The lens in the eye forms the image on the retina. The image formed is real and inverted. The retina is a very delicate membrane containing numerous light sensitive cells.

This light sensitive cells gets activated when light falls on it and generates electric signals. These electric signals are sent to the brain via the optic nerves present in the eye. The brain finally processes these signals and thus we see the object clearly.

The ability of the lens of the eye to adjust its focal length accordingly is called the power of accommodation,

The minimum distance, at which the object can be seen clearly without any strain is called the least distance of distinct vision.

To see an object clearly without any strain is when we place it at about 25 cm from the eye.
