What is the difference between electro and permanent magnet? |
|
Answer» Differences are1. In electromagnet, magnetic fields are produce by electric current while in permanent magnet, magnetic fields are produce by this permanent magnet.2. Electromagnet are generally used for short time producing Magnetic fields in comparison to permanent magnet. 3. We can increase the magnetic field of Electromagnet but we can\'t in that of permanent magnet. In an electromagnet the magnetic field is created through electric current in a wire-wound coil and strengthened by a soft-iron core. As soon as you turn off the power, the soft-iron core loses its magnetisation.A permanent magnet is made of ferromagnetic material, which is magnetised by a strong external magnetic field. The magnetically hard material that is used keeps part of its magnetisation after the external magnetic field is turned off. Permanent magnet strength cannot be change whereas Electromagnet can be change by changing current in it |

How do auxins promote growth in presence of light |
| Answer» Auxin is plant growth regulator which is sensitive to light. It is present at the growing apices of root tip & shoot tip and it promotes the growth of cells. When light falls on the plant, auxin moves away from the light. Therefore, the concentration of auxin increases on the shady side of the plant. Auxin stimulates the growth of cells on the shady side of the plant which causes bending of the plant to the other side. This gives the appearance that the stem of the plant bends in the direction of light. | |
