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

Included Angle when Bearings are Measured in Same Side of Different Meridian

Go Included Angle = (180*pi/180)-(Fore Bearing of Previous Line+Back Bearing of Previous Line)

Included Angle when Bearings are Measured in Opposite Side of Common Meridian

Go Included Angle = Back Bearing of Previous Line+Fore Bearing of Previous Line

Included Angle from Two Lines

Go Included Angle = Fore Bearing of Previous Line-Back Bearing of Previous Line

Magnetic Bearing given True Bearing with East Declination

Go Magnetic Bearing = True Bearing-Magnetic Declination

Magnetic Bearing given True Bearing with West Declination

Go Magnetic Bearing = True Bearing+Magnetic Declination

True Bearing if Declination is in East

Go True Bearing = Magnetic Bearing+Magnetic Declination

True Bearing if Declination is in West

Go True Bearing = Magnetic Bearing-Magnetic Declination

Magnetic Declination to East

Go Magnetic Declination = True Bearing-Magnetic Bearing

Magnetic Declination to West

Go Magnetic Declination = Magnetic Bearing-True Bearing

Fore Bearing in Whole Circle Bearing System

Go Fore Bearing = (Back Bearing-(180*pi/180))

Magnetic Bearing given True Bearing with East Declination Formula

Magnetic Bearing = True Bearing-Magnetic Declination
MB = TB-MD

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.
