@saheransandh Bhai direction of alpha particle is direction of current. Direction of force is north because alpha particle is deflected towards north due to external force.
Thankyou sir for making this video. Preboards are approaching and day after tomorrow (that is 16th December) I have science exam. This video was very helpful for last minute revision. Few topics were not clear but after watching this video, I gained confidence. Thankyou ❤
(d) The direction of the magnetic field can be determined by the Fleming’s left hand rule. According this rule, if we arrange the thumb, the centre finger, and the forefinger of the left hand at right angles to each other, then the thumb points towards the direction of the magnetic force, the centre finger gives the direction of current, and the forefinger points in the direction of magnetic field. Since the direction of positively charged alpha particle is towards west, the direction of current will be the same i.e., towards west. Again, the direction of magnetic force is towards north. Hence, according to Fleming’s left hand rule, the direction of magnetic field will be upwards.
@@user123-f8tAlpha particles mean current flowing from +ve to -ve so current is in west.Now apply left hand rule put your middle finger pointing towards left and thumb inside.So you'll observe your forefinger is upwards.So the direction of field is upward.

- Fingers: direction of magnetic field (B)
*Magnetic Forces*
- Force on a current-carrying conductor in a magnetic field
- Direction of force: perpendicular to conductor and magnetic field
- Fleming's Left-Hand Rule:
- Thumb: direction of motion (or force)
- Index finger: direction of magnetic field (B)
- Middle finger: direction of current (I)
*Electromagnet*
- A coil of insulated wire wrapped around a core
- Produces strong magnetic field when current flows
- Used in motors, generators, and transformers
*Applications*
- Electric motors
- Generators
- Transformers
