Magnetic Bearing given True Bearing with East Declination Solution

STEP 0: Pre-Calculation Summary
Formula Used
Magnetic Bearing = True Bearing-Magnetic Declination
MB = TB-MD
This formula uses 3 Variables
Variables Used
Magnetic Bearing - (Measured in Radian) - Magnetic Bearing is the horizontal angle which a line makes with the magnetic meridian is called magnetic bearing. It varies with time.
True Bearing - (Measured in Radian) - True Bearing is the horizontal angle measured clockwise between the true meridian and the line is called true bearing of the line.
Magnetic Declination - (Measured in Radian) - Magnetic Declination is the horizontal angle between true north and magnetic north at the time of observation.
STEP 1: Convert Input(s) to Base Unit
True Bearing: 60 Degree --> 1.0471975511964 Radian (Check conversion ​here)
Magnetic Declination: 5 Degree --> 0.0872664625997001 Radian (Check conversion ​here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
MB = TB-MD --> 1.0471975511964-0.0872664625997001
Evaluating ... ...
MB = 0.9599310885967
STEP 3: Convert Result to Output's Unit
0.9599310885967 Radian -->55 Degree (Check conversion ​here)
FINAL ANSWER
55 Degree <-- Magnetic Bearing
(Calculation completed in 00.004 seconds)

What is Magnetic Meridian?

It is the direction indicated by a freely suspended and balanced magnetic needle unaffected by local attractive forces. The location of the magnetic poles is constantly changing, hence the direction of magnetic meridian also changes. However, the magnetic meridian is employed as a line of reference on rough surveys.
