Have you enabled the magnetometer?

        //Enable the magnetometer
        writeMagReg( CTRL_REG5_XM, 0b11110000);   // Temp enable, M data rate = 50Hz
        writeMagReg( CTRL_REG6_XM, 0b01100000);   // +/-12gauss
        writeMagReg( CTRL_REG7_XM, 0b00000000);   // Continuous-conversion mode

And are you reading the values every loop?
readMAG(magRaw);

If you still have issues, paste your code here so I can look further.
