Fleming's Hand Rules Explained

The video tutorial explains Flemings left and right hand rules, which are fundamental concepts in physics. The left hand rule helps determine the direction of force on a current-carrying conductor in a magnetic field, while the right hand rule is used to find the direction of induced current when a conductor is moved in a magnetic field. Both rules involve positioning fingers to represent current, magnetic field, and force directions. The video also compares these rules, highlighting their similarities and differences.

What is the main focus of the video?

• Exploring the history of physics

• Learning about Fleming's left and right hand rules

• Understanding the magnitude of forces

• Studying the properties of light

According to Fleming's left hand rule, what happens when a current-carrying conductor is placed in a magnetic field?

• The magnetic field disappears

• The conductor melts

• A force acts on the conductor

• The conductor changes color

What does Fleming's right hand rule help determine?

• The speed of light

• The direction of induced current

• The temperature of a conductor

• The color of a magnetic field

In Fleming's left hand rule, which finger indicates the direction of the current?

• Thumb

• Little finger

• Middle finger

• Forefinger

In Fleming's left hand rule, what is the relationship between the current, magnetic field, and force?

• They are identical

• They are opposite

• They are mutually perpendicular

• They are parallel

In Fleming's right hand rule, which finger shows the direction of the induced current?

• Ring finger

• Middle finger

• Forefinger

• Thumb

What is the role of the thumb in Fleming's right hand rule?

• Indicates the temperature of the conductor

• Shows the direction of the induced current

• Points in the direction of applied force

• Indicates the direction of the magnetic field

How are the three parameters (current, magnetic field, and force) oriented in both Fleming's rules?

• They are parallel

• They are mutually perpendicular

• They are identical

• They are opposite

What does the left hand rule help find when the direction of current and magnetic field is known?

• The speed of light

• The color of a magnetic field

• The direction of force

• The temperature of a conductor

What is the primary use of the right hand rule?

• To determine the color of light

• To find the direction of force

• To find the direction of induced current

• To measure the speed of sound
