An iron rod can be converted into a magnet by passing an electric current through an insulated coil wound around. When the current flows, the iron bar gets magnetized. One end becomes North Pole and the other the South Pole. If the direction of the current is reversed, the Nort..

If one end of a metal rod is placed in a stove, the temperature of the other end increases gradually. Heat is transferred from one end of the rod to the other end. This transfer takes place due to molecular collisions and the process is ca..

In earlier days, doctors used stethoscopes consisting of thin wooden rods with broadened ends. By placing one end to his ear and placing the other end on the patient's chest, he could hear the sound of the heart beats transmitted through the wood. Motor mech..

It comprises of the nerve cells or the neurons. These nerve cells are bipolar. One end of the bipolar cells, synapses with the rods and cones and the other end synapses with the ganglions present in the next layer. There are certain nerve cells called the horizontal a..

Two Kinds of Electric Charges - You can electrify a glass rod by rubbing it with silk. Suspend such an electrified rod by a silk thread as shown in figure. If you bring another glass rod electrified in the same manner, you will notice that the rods repel each..

The best method of making a powerful magnet is by passing electric current. Wind a length of an insulated copper wire around a steel rod DY and connect it to a battery and a switch. After the current has passed through the coil for some time you will notice that the steel rod..

14. - A straight horizontal conducting rod of length 0.45 m and mass 60g is suspended by two vertical wires at it's ends. A current of 5.0 A is set up in the rod through the wires. (a) What magnetic field should be set up normal to the conductor for the tension in the ..

Bundles of muscle fibres are grouped in a fascicule, which are held together and enclosed by collagen fibres and by connective tissue. A tough outer layer called fascia, lying below the skin, surrounds the bundles of fascilli. A highly magnified view of skeletal muscle fibre reveals thread-like st..

Introduction - The phenomenon of electrolysis is an important chemical effect of electric current. In a metallic conductor, the electric current is due to the drifting of free electrons, there is no chemical or physical change, only the generation of heat. However, in ionic solutions (electrolytes)..
