1.	It is established that an electric currentthrough a metallic conductor produces amagnetic field around it.Is there a similar magnetic field producedaround a thin beam of moving(i) a-particles,(ii) neutrons? Justify your answer.NCERT Exemplar
Answer» In case of movement of a charge particle, magnetic field is created around the path. Since alpha particle is positively charged.So magnetic field would be created. In case of movement of a charged particle the magnetic field is created around the path on which the charged particle moves. (i) Yes, a thin beam of a-particles (which are positively charged) is like straight conductor carrying current in the direction of motion. (ii) No, as neutrons carry no charge so no magnetic field would be created around its path.

In case of movement of a charge particle, magnetic field is created around the path. Since alpha particle is positively charged.So magnetic field would be created.

In case of movement of a charged particle the magnetic field is created around the path on which the charged particle moves.

(i) Yes, a thin beam of a-particles (which are positively charged) is like straight conductor carrying current in the direction of motion.

(ii) No, as neutrons carry no charge so no magnetic field would be created around its path.
