Скачать или смотреть NCERT Class 10 Physics Chapter 12 | Magnetic Effects of Electric Current Part 5 | By Shaheen PCME

In this video, we’ll learn about one of the most important topics of Magnetic Effects of Electric Current —
Force on a Current-Carrying Conductor in a Magnetic Field and Fleming’s Left-Hand Rule 🔥

🧲 Step-by-step explanation includes:

Understanding how a current-carrying conductor experiences a force in a magnetic field

Activity to demonstrate the direction of force

Detailed explanation of Fleming’s Left-Hand Rule

Direction of Magnetic Field (B), Current (I), and Force (F)

Important for Board Exams & Conceptual Questions


🎯 Explained clearly and practically By Shaheen PCME


3️⃣ Activity

🧪 Activity to Show the Force:

Take a small conducting rod and suspend it between the poles of a horseshoe magnet.

Connect the rod to a circuit with a switch and battery.

When current flows, the rod moves — showing that a force acts on it due to the magnetic field.

Reversing the direction of current or magnetic field reverses the direction of motion.


2️⃣ Fleming’s Left-Hand Rule

👉 Rule:
Stretch the thumb, forefinger, and middle finger of your left hand mutually perpendicular to each other.

Forefinger (First finger) → Direction of Magnetic Field (B)

Middle finger → Direction of Current (I)

Thumb → Direction of Force (Motion)


💡 Remember:
“FBI Rule” – Force (F), Magnetic Field (B), Current (I)
