Magnetic effect of current- Very Short Answer Questions

1. What happens if a current carrying conductor is placed in the magnetic field?

The conductor experiences a force and the direction of this force is given by Fleming’s left hand rule.

2. On what effect of an electric current does an electromagnet work?

An electromagnet works on the principles of magnetic effect of current.

3. Name the alloy which is mainly used for making permanent magnets.
The alloy ‘Alnico’ is used for making permanent magnets. It is an alloy of aluminium, nickel, cobalt and iron.

Carbon and its compounds

Revision Notes on Carbon and its Compounds Two or more elements combine to form compound. There are two types of compounds-  Organic Compound  and  Inorganic Compounds . Organic compounds are the one which are made up of carbon and hydrogen. Covalent Bond The bond formed by sharing a pair of electrons between two atoms are known as  Covalent   Bond . Carbon forms covalent bond. Carbon exists in two forms- as free state and as combined state. Free form of carbon is found in graphite, diamond and fullerene. In combined state, carbon exists as Carbon-dioxide, Glucose, Sugar etc. Allotropes of Carbon Different forms of an element that has same chemical properties but different physical properties are known as  Allotropes . There are three allotropes of carbon- diamond, graphite and fullerene. Diamond Diamond exits as three-dimensional network with strong carbon-carbon covalent bonds. Diamond is hard in nature with high melting point. It shines in presen...

Reflection of Light Question 1: What happens when a ray of light falls normally (or perpendicularly) on the surface of a plane mirror ? Solution : As ray of light falls normally on mirror, this means that angle of incidence is 0o. From second law of reflection, we know that angle of incidence is equal to angle of reflection. So, angle of reflection will also be zero. Therefore, the light ray will be reflected back along the same path. Question 2: A ray of light is incident on a plane mirror at an angle of 30°. What is the angle of reflection ? Solution : According to the second law of reflection, angle of incidence is equal to the angle of reflection. Therefore, angle of reflection=30 0 Question 3: A ray of light strikes a plane mirror at an angle of 40° to the mirror surface. What will be the angle of reflection ? Solution : Angle to the mirror surface=40 0 Therefore, angle of incidence= 90 0 -40 0 =50 0 According to the second law of reflection, angle of incidence is...
