Nama saya Jia Xin and I look very tired. Today we celebrated SG's birthday in advance. SG for my country. And SG for Stephanie Goh. 😘 #SG54 #SG27 https://www.instagram.com/p/B05wgw4nlF14elh7rfSOIuUvCDp_d_fOZKDHjA0/?igshid=8xdrfmw3j4db

Fleming's Left-Hand Rule

Fleming's left-hand rule can be used to determine the force exerted on a current carrying wire in a magnetic field.

For this rule you need to hold your thumb, index finger and third finger at right angles to one another.

-Your thumb represents the force (F)

-Your index finger represents the magnetic field (B)

-Your third finger represents the conventional current flow in the wire (I)

Note: The FBI can be helpful when trying to remember the rule

The Right-Hand Grip Rule: Magnetic Fields

Where there are moving charge carriers there will be a magnetic field. The 'right-hand grip rule' can be used to determine the nature of the magnetic field surrounding a flow of charge carriers (electrons in the case of a metal wire). Your thumb is used to represent the direction of conventional current flow (remember conventional current represents the flow of positive to negative), and the gripped remaining fingers show the magnetic field as a result of the moving charge carriers.
